4path waveguide
The custom 4 PATH-designed waveguide allows precise coverage while also delivering an excellent, linear high-frequency response. The unique shape of the four ducts forming the guide creates an ideal isophasic load from the vocal range up to the highest audible frequencies.
Consistent robustness
Reduce the commissioning time on your new projects with HVL’s modular array-ability, multiple directivity indexes (Q, and small footprint in comparison to its power. HVL can lower overall system costs by delivering full coverage with fewer modules precisely matching the audience area. Rated for direct-exposure outdoor installations, each cabinet is made of Baltic birch plywood with polyurea coating and includes a weatherproof barrier strip for connections. The grille is powder-coated heavy-duty steel with open-cell fibers and water repellent woven-fabric backing.

1 Year Later....Still going Great
Color: Black
Ok, I have had this keyboard since June 28, 2015 and today is July 4th, 2016.
Having thought about this keyboard over the last year and then swapping it out for a standard Dell (non ergonomic) keyboard for the last two weeks has made me realize a few and not so few obvious things:
1) Footprint of ergonomic keyboard on desk is larger than most that I can recall. Not a con but keep that in mind if your computer desk is on the smaller side
2) Build Quality. You buy a top tier (Microsoft, Dell, Lenovo, HP, etc) business OR retail keyboard for a decent price, one EXPECTS minimal issues. There are two issues that have cropped up over the course of the last year: a couple of the tabs holding the snap on palm rest have broken off. The palm rest/riser plastic piece is still firmly attached. My guess is that these plastic clips were put in high stress areas. No loss in functionality. The CAPS LOCK LED light that is in the middle doesn't really work anymore. If I hit the caps lock with my left pinkie finger, the light doesn't come on. If I smash the same caps lock with my thumb or index finger, the light comes on and then goes out. Windows 10 always tells me via the popup message if my caps lock is on. No loss in functionality.
3) Key labels have not worn off. The letters are a bit faded but are still clear. The number row above the keys are virtually pristine (and by extension are used for the comparison of the letter keys).
4) This is a very good ergonomic keyboard. Within a couple of days of the swap, my wrist and left finger were starting to have that familiar hurt.
I could go on and on about the specifics that some have posted in other reviews, but I feel that this is relevant to my use after a full year

IMHO: Expensive torture for thumb, hand, and arm
Color: Black
I should have paid more attention to the clearly reasoned (and IMHO *accurate*) negative reviews. After about one week of not-very-intense use I had to stop using this apparently well made but horribly designed keyboard. The use of my right hand and arm became painful. There were three main problems:
#1 The amount of thumb pressure required to actually register the "space" key was way too much to type with any comfort or confidence. Even if I concentrated on always striking the space key so that a space would be inserted into the text or computer code where needed, I found that about 1-in-12 or 1-in-14 attempted spaces would not be inserted. It is terrible that part of one's brain must focus on striking the space key with heavy force; it is even worse that one must proof read each page of text or code to ensure that spaces have been inserted where needed.
#2 The space key is intrinsically badly designed anyway, because one wants this key to be equally welcoming to both the left and right thumbs. It isn't. I found that my right thumb worked best, requiring unnatural contortions to ensure spaces were inserted where needed.
#3 In general, I found that the $10 keyboard Dell included with my latest XPS desktop requires a more comfortable amount of force for ALL of the keys, not just the space key. This could be because the Microsoft Ergonomic Keyboard 4000 for Business requires greater downward movement of the keys for a stroke to be registered.
Problems #1 and #2 are so severe that I found this keyboard simply unusable. This is quite an indictment for a way-above-average-cost keyboard that is allegedly designed and built with proper ergonomics in mind. I am astounded that so many users find this a comfortable keyboard. By the way, during more than half of my PC and computer keyboard use, which dates back to the late 1970s, I have actually used (and preferred) Logitech and especially Microsoft ergonomic keyboards. This is the first ergonomic keyboard I have ever used that I have found to be a thinly disguised implement of torture for thumb, hand, and arm.
I now have some appreciation for the feelings of the other one-star and two-star reviewers when they read the patronizing remarks of the many keyboarders who find this device comfortable. Some seem to pooh-pooh (usually in patronizing terms) those of us who find this one of the most wretched keyboards we have ever encountered. It is a little hard to believe we sufferers happened to receive slightly defective devices. The complaint I offer can be found too often in the reviews for our complaint to occur as a result of a minor or rare manufacturing defect.
On the plus side, the build quality appears to be terrific.

High quality stand
Style: Swivel Base, Color: Silver, Style: Swivel Base, Color: Silver
The mStand 360 is an amazing stand. I love how it is built from a single piece of aluminum and looks amazing on my desk. It fits my Macbook Pro 15" extremely well and raises it up to the height of my monitor easily. Not only does it help me improve my posture, but it also neatens up my desk significantly. I can easily fit an external keyboard under my Macbook when I am not using it, clearing up space. The hole in the back is also useful for bunching cables together that go directly into my Macbook, keeping my cables off the floor when I take my Macbook to go somewhere.
The stand feels very stable, with no chance of my Macbook falling off. The aluminum C shape does have a slight bend on it if you put extra weight on it, but all in all, it feels very sturdy. The rubber padding on the stand also keeps the stand from scraping or damaging any part of my laptop and I feel very comfortable trusting the stand with my laptop. I would not recommend typing on a laptop keyboard while it is on the stand, but it works great with external keyboards.
The swivel feature met my expectations, allowing the laptop to be easily turned. Thankfully, it was not too easy to turn and my laptop does not turn itself when in the stand. It is a nice feature to have, especially because I paid only 5$ extra for it (the price for the swivel stand seems to have increased since then).
I am very happy with my purchase, even though it did seem a little expensive. I am wholly satisfied that I spent the extra 20$ to get a great laptop stand that will probably last for years.

This stand is just perfect!
Style: Swivel Base, Color: Space Gray
I first started looking at stands when I learned that staring at a laptop for hours can cause back injuries.
So, I got the idea to use a stand, at home. This stand allows me to have a keyboard and mouse and use my laptop as a glorified desktop with a smaller monitor.
I was astonished at the quality of this stand. It is better built than it needs to be, but I am not complaining at all about this. Let's face it, we spend a lot of money on our laptops, and you want to have a great platform to sit your laptop on.
I love the ability to swivel the stand. My desk is very close to a window that lets in a lot of the sun at certain times of days. This would result in a glare if not for the ability to spin my computer ever so slightly in either direction to combat this problem.
Also, it is a great cable manager with the hole on the back of the stand that makes everything look cleaner and more organized. The color matches my MacBook perfectly and looks like it is an Apple product.
Summary:
Great product. High quality. Looks great. Swizel is impressive and useful.

Perfect stand for your Apple products
Style: Swivel Base, Color: Silver
I loved the look and design of this stand so much that I bought two of them, one for my work office and one for my home office. I have a 13" Macbook Pro and the screen sits at the perfect height for me. I do not feel like I am straining my neck looking down at my computer screen anymore. At both my work and home offices I have Apple display monitors, so now my laptop screen is inline with my monitors, AND matches their bases, which is very nice.
The keyboard is at a nice angle and isn't too high off the desk if you need to use the trackpad or keyboard. However, I recommend using a secondary keyboard and mouse. The keyboard sits about 4" off the desk so there is room to store your secondary keyboard and mouse underneath the stand. But because it is 4" off the desk, it makes it uncomfortable to type on the laptop or use the trackpad for an extended period of time.
The cord keeper hole in the back of the stand is a nice touch, however if your cords are too tight, it will rotate your stand. The swivel is a nice touch, but it is somewhat sensitive. So far no accidental bumps have irritated me, which was one of my concerns before I purchased. All-in-all I would recommend this product to anyone who uses their laptop with a secondary display, regardless of if you use Apple products or not. It is a well made stand and looks good, and seems like it will accommodate most laptops (within the manufacturers guidelines).
