I have a few. Good customers service and trustable but of course they are chinese. To be honest i excpected worse but till now the lasers from them give correct values. Like the 7 Watt one is also 7 Watt i checked. A couple of years back i bought there a few and till now they all work fine. The prices are fine (not for all) but you can buy better custom made they are not only cheaper but they are excactly what you asked. But for chinese with there brand on they are the better company to buy from. That is my opinion about Zeus lasers. Just look very good and compare prices.
Try my lasers @ JLasers.
Theyre affordable. I hand-make every one. (not the host but the internals)
I am from Canada, so very fast shipping times, and I have excellent customer service, I reply within the hour usually.
I also offer lifetime warranty.
