Received different products than ordered (LED Bracelets). Working with seller to rectify. Initially thought it was an honest shipping error, but I see two previous reviews experiencing the exact issue.
Looks nothing like what is pictured, is not adjustable, in a white sleeve with velcro ON TOP OF THE ON/OFF SWITCH. If you put it on and press the velcro together to fasten, you have to toggle the on/off switch; there's no way around it. I've accidentally turned it on so much that the battery drained before I got any real use out of it. Doesn't seem to do much beyond red, and only half the strip lights up. I haven't investigated it much since I was just disappointed in it as it came, threw it into a scrap box; maybe it will become part of another project one day. At least it didn't cost much.
