FAQ
I would like to perform a heating / cooling program where the temperature ramps from one set point to another over time. Are the PolyScience 28 Liter Stainless Steel Open Bath Systems capable of this?
That depends on the controller used. Only the Advanced Programmable controller can be programmed to perform ramps.
It is possible to have the circulation on without any temperature control being on?
No. If the circulation is on, then a temperature setting must be selected.

A Genuine Game-Changer for Manufacturing Management
Color: Matte Black, Clear Lenses, Size: Standard
A Genuine Game-Changer for Manufacturing Management
These glasses have been nothing short of life-altering for my career. As a production manager overseeing a manufacturing facility, documenting Standard Operating Procedures (SOPs) has always been a significant hurdle. My primary goal in purchasing these was to record high-quality POV video of processes, which I can then feed into AI tools to generate written SOPs. This isn’t just a win for my productivity; it’s a win for my crew, as it finally provides them with the clear documentation they need to succeed, relieving me of the stress that comes with inconsistent training materials.
**Design & Comfort**
I initially opted for the larger frame, but the height was a bit much aesthetically for my face. The standard size, however, is excellent. I have a history of headaches from standard eyewear after long days, but these remain comfortable for extended wear. They are impressively discreet—I had multiple people compliment them on day one without ever realizing they were smart glasses. They are convincing enough to pass as normal eyewear to the untrained eye.
**Performance & Battery**
* **Video & Audio:** The video quality is surprisingly clear, and the microphone performance is exceptional. I’ve taken several calls while wearing them, and the recipients couldn’t tell the difference between these and my phone’s handset. The audio is solid—provided you keep your expectations realistic regarding the low end. The bass is sufficient for daily listening.
* **Battery:** This is the one area that requires adjustment. You’ll get about 30+ minutes of continuous recording, which drains the battery quickly. However, the charging speed via the included case is remarkably fast, which helps mitigate the downtime.
**The "Unexpected" Features**
While I bought these for SOP documentation, the note-taking and translator features have been revelations. On the production floor, I’m constantly pulled in four different directions. When I need to track material requests or quick process changes on the fly, these allow me to capture information immediately so nothing slips through the cracks. It has turned a single-use tool into an all-day essential.
**Verdict**
I am currently investigating sourcing safety-rated lenses to integrate these into my daily shop-floor workflow. While the frames themselves aren't officially safety-rated, for office-based procedures and light floor work, they have already become a staple of my daily routine. Between the hands-free note-taking, clear communication, and the efficiency they bring to training, these are an incredible value for anyone in a management or technical role.
**Pros:**
* Excellent microphone and video clarity.
* Inconspicuous, stylish design.
* Invaluable for hands-free documentation and note-taking.
* Fast-charging case.
**Cons:**
* Battery life is limited during heavy recording sessions.
* Frame is not officially rated for high-impact industrial safety environments.

Impressive Smart Glasses for Recording and Everyday Use – Very Cool Tech
Color: Matte Black, Clear Lenses, Size: Standard
I picked up the Ray-Ban Meta (Gen 2) Wayfarer mainly for hands-free recording and the AI features, and overall it’s a really cool piece of wearable tech. The design looks just like normal Ray-Bans, so they don’t feel gimmicky or overly “techy” when wearing them in public.
The camera quality is surprisingly good for glasses. Video and photos come out clear, and it’s incredibly convenient being able to record exactly what you’re seeing without pulling out your phone. Audio capture is also solid, and the open-ear speakers work well for calls and quick media playback.
Battery life has been noticeably improved compared to earlier smart glasses, and they’ve been reliable during regular use. Pairing and app integration were straightforward, and once set up, everything just works in the background.
My only real disappointment is that there’s no integrated screen or display. For a device that can see what you see and has AI capabilities, having some kind of built-in visual feedback would have made the experience even more powerful.
That said, as a recording device and AI-assisted wearable, these are genuinely impressive. If you want discreet, hands-free video capture in a stylish form factor, the Ray-Ban Meta Wayfarer is a very unique and well-executed smart device.

Not Perfect but Nice 👋
Color: Shiny Black, Green Lenses, Size: Large
Looks like regular sunglasses. 🤙 The AI is pretty basic. The responses are basic. Battery life is fairly good and the case as a portable charger extremely cool. Why did I get these? FOR THE CAMERA.
The video recording is good. Good picture quality and this is the only camera glasses with image stabilization. When manufacturers make wearables recording video image stabilization is a must. Here its good. The footage is not shaky. But this coolness is only available in 1080p even though this records 2k or 2.7k. The app works fairly good but a tiny bit finicky as videos are not always loading to your gallery on phone or app automatically.
The app in general is cool in creating some videos but again basic and limited with restrictions.
The thing I don't like is connecting to an app which all these companies do to grab your data. Seems to be more about the app than the product.
They only things that bug me about this is the 5min recording limit and the flashing light that is a distraction to the person being filmed. There are no blinking lights on our cellphones when recording. You can turn off LED blinking lights on all cameras but here they claim some privacy issues.
When in public there is no right to privacy. When in private property and you suspect anyone recording with anything and you don't want it then say so other than than that there are cameras everywhere. They can record us but we can't record them? We don't need the blinking light and we need longer record times.
I would like a seperate SD slot so I don't have to connect to my phone all the time to pull footage. These aren't waterproof so... This is a quality product with good audio and video. Interested in any updates to turn off the blinking LED and recording time extensions.
