Bought 6 items. Battery lasts 24h+, more than promised (tested with blue light). On/off button needs redesign, too big an sensitive. Needs also better pink color. One or two auto programs were not able to sync between 6 units because 1 unit had been programmed with different color sequence start. Most will probaby use just color option and not use auto at all, but they aren't bad also. Main colors are very bright (RED, Green) but bluish are also nice, almost neon and darkest blue provides a little bit UV ( test in complete darkness ). Ability to change speed is good. Light output pretty good, small rooms get nice ambient light. They are very light, packed 6 into special carrying case and it doesn't weigh at all. I had problems with different light outputs out of the box for two units, but they disappeared after I played with auto programs, and fully recharged them. I wish legs were black, so I'll repaint them. I've been using also Astera AX1 tubes, and for some events I'll be now using these tubes, as Astera cases are very heavy. These are way better than ADJ's. Will probably order extra 6x.
