We use mobile disco in the past two years. We mounted two sets of 4 magical wash or 8 in all.
These are the only by LEDs that we had, but we could see others at work and do not regret ours.
Pros: Powerful, fast strobe, very light, used in DMX or auto, dimmable ... I love the opportunity to use the purple (by mixing) to make a UV effect with a very good record.
Cons: a bit fragile, you take care, but one of them to have an insert for later (for tightening wheel) is broken.
Value for money: There is still good despite the fragility, Considering the strength and number of LEDs for 59 € coin coupon that remains hard to beat.
It was on that some are led by a thirty euros, but with LEDs weaker and fewer in number, therefore no returns.
With experience I will ever be that choice without hesitation, it's not as powerful as traditional 56 pars, but the possibility of varying colors, to strobe and the grader is really appreciable discomobile.
