Review on Dreamcolor SPARKE Backlight Non Waterproof WS2812B by Hunter Wyn

Rating updated. The manufacturer splices light strips into endless strips. The first device I received had a loose connection, actually cold-soldered. I only noticed it after I finished installing, and at that point I couldn't uninstall it or try to fix it myself. About 40% of the bulbs do not light up due to cold soldering. I couldn't find a way to request an exchange on the web form and Rewain advised me to return it. Unfortunately, once the return started, the seller got back to me and politely offered an exchange. I decided to order a new one and check it out carefully. The new item is correct and working. I advise all buyers to carefully inspect their LED strips to ensure there are no loose solder joints. I enclose a photo of "good" solder.
