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)

Matter-enabled High Quality Light Strips
Size: 9.8ft
Great lights. Used these as accent lights behind an entertainment center to avoid harsh overhead lights. Three in total. They put out plenty of light and easy to install and use. Love the Matter integration.
Negatives: can’t use the cut portion. Once it’s cut, the extra is useless.
Not cheap for a light strip. Purchase if you like the light tech or want Matter integration.
You have to guess for “light temperatures” (warm, daylight, etc.). I used a Google search for finding the Hex # to input into light control and fine tune from there
Love these and would buy again

Great product, reliable quality!
Size: 9.8ft, Size: 9.8ft
I moved into a new place with wood stairs. There’s a landing step that is invisible at night - it just looks like the floor below the step. Of course, one can only determine a stair to be invisible at night after one misses said stair, falling, twisting ankle and foot, lying on floor cursing and crying for help from the husband at 11pm in the dark.
I used painters tape for a couple of weeks. Again, not so helpful at night but there was some distinction. I knew I needed to light this step up to avoid future slips on the invisible step.
I love Govee products. I have a Govee metal tall skinny lamp thing which is where I learned about this gummy, straight, light tube that they make. I really did not want the light strips that were cheaper w the separate little lights on them since this was going under a stair and you could see the underside of the stair clearly from our lower living room whilst sitting on the couch.
This product was SUPER easy to install. I love that you can cut it to size (though if you need exact I would go with the Govee light strips w the little lights there’s more cut areas closer together).
I love that I already have the Govee app and it connected relatively easily (turning things on/off, using airplane mode and unplugging will get you connected).
My 2 gripes about Govee…
1. Please figure out how to make strips that you can cut and connect - I want to be able to configure a corner or different shape besides just a straight line. I also want to be able to connect multiple lines to one adapter (I had a cheap one that could do this but I was afraid it would burn my house down). I paid $$$ for a single step and would like to have been able to use the rest of my strip for another step but instead it’s just useless.
2. I wish it dimmed a little more - the 1% is really bright in the dark. This strip is VERY bright.
Anyways, love my step and it’s safe to take the painters tape off and have it be a normal step.

Bright, with great diffuser
Size: 16.4ft
This is a nice, flexible light with a good diffuser. The tape is sticky, so make sure you want this to be permanent, because it's likely to damage wall paint when removed.
Lot's of color, pattern, and dynamic light options with the software. My last Govee light strip had the green LEDs burn out after a year, hopefully that's not the case here. I will update this review if that happens. These are pretty pricey, so hopefully they're durable!
