Solid surge protector, but some outlets are a tight fit
Size: 6 Ft, Color: Black
For the price, this power strip covers all the bases — 6 outlets, 3 USB ports, and a generous 6ft cord that reaches exactly where you need it without having to rearrange furniture. The surge protection at 1680 joules gives me peace of mind having it near my electronics, and the ETL listing confirms it meets safety standards which is always reassuring with electrical products. The USB ports are a nice bonus and charge my devices at a decent speed. My main gripe is that some of the AC outlet slots are noticeably stiff and tight, making it genuinely difficult to plug certain things in — I had to use a bit more force than I was comfortable with on a couple of them. It loosens up slightly with use but out of the box it was more of a struggle than it should be. Not a dealbreaker but something worth knowing especially if you're plugging in bulkier adapters. Overall a good functional surge protector for a home office or dorm room setup at a very reasonable price

Great thick surgery protector
Size: 20 Ft, Color: White
I am so glad there was a 20ft option. Our house is 104 years old and sockets were very scarce. I guess when we updated the electric we should have added more sockets lol I have a desktop Coca-Cola fridge and I run a desktop Vornado fan year round. So this was the perfect length to plug these 2 items in. I liked that this has a large extension cord on it. Feels very furable and that it has more meat in it yo protect my items vs the thin corded ones. It also has places to charge USB or USB C. Love the design a lot. Having the prongs turned to add from side works perfect and leaves more room for additional plugs. Very portable and no noise whatsoever.

Easy assemble and not to big!
Color: Black, Size: 132in-Large Metal Base
I bought this because I fo a lot of zoom/teams meetings and work just mandated no false backgrounds (don’t ask) soooo to hide my real home and allow others to roam free while I work I got this. Easy to assemble although you will need some space. I thought I might be to big at 11’ wide as I have a small desk area but actually it’s perfect and could use a couple more panels. Leaves just enough room so I’m not completely cocooned - I can move my chair and get up walk behind chair and exit space. Great deal and tax deductible!
