I purchased two sets of these as I was looking for IP65 rated fixtures which also had built in motorized zoom, and these were perfect. The colour mixing is excellent leaving no 'shadowing' (which is sometimes found on cheaper fixtures with the RGB LEDs). The menu is easy to program.
These are very well built and of good quality. The rubber seals around the connectors are very good. Please note that these have 5 pin DMX connectors on them so you will need to purchase cables if you dont have them as these did not come with DMX cables. These do come with power cables however I used my own Neutrik Powercon True1 male - female cables to link these.
I would recommend getting these flightcased in pairs, making it easier for one person to manage the weight.
Overall, I am very happy with the product.
