Well this is the first time you posted "for the cheap price its ok" on any laser unit as you seemed to compare them to top notch builds.
As for the $90 Pocket Meter the experts say that it might have $10 worth of part's and for a price of $25 or $30 I could see.
There was a very good Hyperion 2W LPM for $75 being sold that many members have. A no brainer which of the two to buy..
I offered "Tommy" aka. Laserpointerstore $40 for his Pocket meter and told him I would test it 5 times a day for 2 weeks only with lasers outputting from 30mw, 150mw, 500mw, 1W, 2W, and 5W. Plenty of cool down in between runs and treated proper, and I would give it back to him and I would pay the shipping.. He said NO... Not much confidence in his meter is there..
You really haven't also noticed just how many new member threads are about ""Help me please my "Thor" or "Gattling" type laser is broken and I only used it once or twice, or just yesterday.
