Received them today, the green laser is a 303 laser but the other 2 are in a different host. Not the one advertised but a nicer one than 303. It is indeed a 405nm so I filed a dispute with PayPal.
I haven't lpm tested them yet but I can say with confidence that none of them are anywhere...
If you don't have anything useful to say why say anything at all? It is well known sanwu is a good company here and podo is a member here on LPF that I believe runs sanwu. Do more research before telling other people to do more research.
No, shipped first class from china is going to be awhile. Last update is June 2nd said cleared customs but unclear if it was china or USA customs. Tracking number does not show anything on USPS as of yet (only trackable on china post) so probably will be awhile.
If you go with the build I recommend you you can add a graphics card depending on budget
The cheapest I would go with is a 5600XT or RTX 2060 which are around $300. Best bang for your buck is a 1660ti though which is around $250
