I've heard olike is a decent place to buy from. Not the best, but not one to avoid. I haven't ordered from them, but know members that hav had good experiences
It's likely a 638 Mitsi....you could build it yourself with a host kit for about the same price and get more power. Just remember beam divergence is terrible with 638's.
My thoughts too. Well I know mr no4a just got his olike from a friend of mine and from what I understand is very happy . If that's a laser that tickles your fancy, then go for it.
The o-like laser looks very nice ... However the heatsink is super small. I had a 400mW 405nm from them in the same power-rock host ... It died after a month or so. And I didn't use it much.
This is the actuall point in time when I started to build lasers. About a year ago.
I am not trying to sell my lasers ... but I do build 500mW 635nm for around $130 - $150. Depends on host etc ...
Blord also build customs lasers in the 501B host like me. You can also ask him about a 635nm laser. Again , blord builds and my builds has a better heatsink than this power-rock host.
There are also much more builders here at lpf ... Try one of them before buying from chinese companies.
