my core required tinfoil in the cap to work, minor complaint but they should have better engineering. my executive classic (15mW) started mode hopping, flickering, then died completely - 14 hours after it arrived at my house. sent it back for an RMA, have one that works now, but it is unstable as hell, going dim-bright-dim-bright-dim-bright. my pulsar is as fine as a pulsar can be - but the pulsar has inherent design problems - no voltage regulation, which is why putting lithiums in a pulsar will kill it, it has a fat useless beam that can't burn a thing unfocused despite being supposedly 125mW, and the button is far too sensitive n picky. it's so crap that it's going to senkat to essentially have it's guts ripped out and replaced - focus mod, new better diode, possibly voltage regulation.
as for the rest, their supposed laser "community" is a bunch of crap, used to be ok when you could mention "other laser companies" but now it's just a propaganda machine, posts about broken lasers or criticism of wicked lasers or tech lasers disappearing. their company has worse business ethics than microsoft, and that's saying something. they sell cheap overpriced crap, and their "affiliate" sells what look like great deals, but are almost certainly counterfeits, and are overpriced for counterfeits. their affiliate also seems to think that they invented orange lasers, invented heatsinking on lasers, and sell the only blue laser in existence that has a blue beam (go read the descriptions on their website of their blue and orange lasers). so, yeah, that's my problems with wicked lasers and techlasers.
