The dimensions are incorrect. Product is listed at 10mm width, but its actually 12mm which is a big difference and for those that need the 10mm specific size this will NOT work. Correct your listing to avoid others being misled !

EDIT..... They look amazing. Couldn't wait to try em with my arduino and make some Christmas patterns. Received the order on the 2nd hooked them up today and they don't work. Super bummed about that. May be just a solder point somewhere but idk. Maybe yours will work but mine didn't and I ain't got the time to return them 😭.******EDIT******I Did end up getting them to work, it was a bad solder point on the red power input. As soon as I hit it with some fresh solder lit right up. It happens all the time. The manufacturer emailed instantly after seeing the post and said they would send out a new one but I never responded and fixed it myself and by no means fault them. It was great they emailed without me contacting them and a simple fix with no time wasted is OK with me. I'll buy again from this company. Happy new year.

Not too impressed with these. I usually buy things like these for cheaper straight from China with better quality control. These say on the package, “Strip should not be collided or crushed”. Well guess what, the one I got was pretty mangled as you can see in the picture, and I was not impressed. Adhesive backing was not real 3M stuff as in the product picture, but some cheap stuff that doesn’t really stick. I did test them and the whole strip seemed to work so that’s good I guess. They’re useable but not in good shape. In the future I will not order light strips from Amazon because although the shipping is quicker, they are about twice as expensive as getting them on AliExpress from a reputable supplier.

Used on a Ender 3 V2 as a lightbar. Bright and colorful when configured correctly with a good light density for the application.This will not work on a stock ender 3, I am using an RPi3 to host Octoprint to control the printer, and Klipper to actually handle the GCODE and motor commands. This firmware gives me access to the GPIO on the board that you need to control the lights, since they are not just a power it and forget thing like normal RGB strips. I am using the header on the mainboard (V4.2.2) that was meant for the screen.Comment if you want more info about kipper/wiring/code/etc.

If you like blinkin lights then these may be for you. There are so many similar items on the market that these don't really stand out but these were the size, pitch and price that I liked so they are perfect for me. Now I just need to completely redesign my driver as the ATTiny85 I wanted to use doesn't have enough memory to run the whole string. I didn't realize that while I was calling the function on individual pixels and only using a couple variables the function itself has to build an array of all the pixels to send the data out in one burst. Live and learn eh?

LEDs DOA. I am using two separate power supplies for the Raspberry Pi and another for LED strip (5V10A). There is still no light even with proper wiring to GPIO and ground pins to LED. Currently waiting for WS2812B controller from manufacturer to test. Will update this review once this issue is resolved.------I contacted seller/manufacturer and finally received working LED strips!
