Exactly what I needed
Color: Black, Size: 34"- 3 Panel, Color: Black, Size: 34"- 3 Panel
It was easy to put together even without a power drill. Completely opaque. Only a very small slit between poles. I plan to add black electrical tape, but that's because I don't want nosies peeking through to see my screen. The height is beautiful. I was afraid it wouldn't be as tall as I needed. But it is perfect. I share a small office with a good buddy of mine. People passing by our door is distracting and invites them to speak to me. I needed something that would stop the former and prevent the latter, especially when I'm deep in concentration mode. The two panels are enough to block outsiders and the third panel I will employ when I can't even be disturbed by my officemate. It's the fastest and easiest signal not to disrupt me at all. 10/10

Packaging contents
Color: Grey, Size: 34"- 3 Panel
Item is as described however this one appeared to be open and some parts possibly used. Example pole packaging mislabeled one had the letter K as a part there is no letter K item in the instructions. Another pole part had a taped on letter A which is completely different from the others thus indicating that it was opened or substituted. Finally after the partition was completely put together one of the bottom screw connection anchors came out making the partition unable to stand. I'm going to have to rig something up in order to get the anchor connected to the bottom panel. In closure the partion could be very acceptable and do the job if it was new and parts labeled correctly. I have pictures of all parts and packaging errors. Would buy again if new. I'm going to pursue some kind of compensation.

Great product
Color: Grey, Size: 34"- 6 Panel
This room divider is great. It was easy to put together. I was worried about it standing up right and not falling over. It stays up perfectly and is very easy to move and adjust to the shape I want it. Also, from one of the videos I watched it looked like the fabric was puckered in the panels. That is not the case at all. The fabric fits tightly in each panel for a nice smooth look. I would definitely recommend this and would buy again if needed.

Awful.
Color: Black, Size: 22"- 4 Panel
Easiest one star review ever. I'm writing this with bloody fingers from assembling this. Multiple poles were bent, none of the pole connectors worked, the hex wrench broke in my hand, the screws didn't really go into the holes provided (I had to get a friend with a press drill to widen the holes to make it work), there are sharp edges on the poles where there is a seam, and doesn't look that great once assembled. Easy do not buy, the only reason I didn't return is because it would have been tough to disassemble the half I got through in the first 5 hours of building (mostly spent fixing the product delivered)

GET A VARIETY SET TO DECIDE WHICH FAVS TO BUY NEXT TIME. YOU’LL LIKELY WANT MORE FRESH OLIVES
Flavor Name: Green & Kalamata, Size: 4 Ounce (Pack of 5)
I did learn of these on Shark Tank and was glad I could try them through Amazon. (I discovered the lemon garlic variety was the one I enjoyed most, so I reordered just those next time.) These are fresh-tasting and hard to stop snacking at one 4-olive serving. If I had guests over, it’s something others would also enjoy. Nice that they come in zipper pack to keep them fresh.
