I have had four of these pars for six years, no issues, good light. For a band playing pubs, clubs these will easily do the job. Brighter than you think, good coverage, and rich colors.
Sound to light is not the best, too sensitive, even when at its lowest setting, however, possibly ok in low to medium-level gigs. Use a Dmx controller (it is how you get the best out of these lights) although be aware, ch1 is not Red, many controllers are fixed 1R,2G,3B..... and this light will not work correctly. I use Adj Operator 1 192, there are so many good copies (for not much money) of this unit and give you everything you require.
You may also be interested, four of these on a T bar fit into a padded keyboard bag, perfect for travel, good protection.
