300mW red eBay laser review

A few people have come across this laser.

Its 300mW 660nm from eBay.

Here is a review:

Packaging:

Cheap - No case. Not good.

Battery:

Comes with a odd battery size, I dont even know what size it is.... It is 3.7V at 2800mA they are re-charable and came with a battery charger that is a nice touch  

Laser shell:

It made of black, good quality alimunium, but only have a duty cycle of 40 seconds on-10 seconds off  :-?

Laser-in-action

Very bright and burns very well ;D


PROS:

High-powerd, No scam, Fells good in the hand and has a constant On-Off switch!

CONS:

Not collimated properly, only burns at a certan point (focus point). The 'focus point' can be moved if you ajust the focus cap. Not very good build quality.

RATING:

7/10

Buy if you want high-power and you want it dirt cheap!! (£80) If you got more cash to spend, DONT BUY!

And thats that!

P.S: I have attached this video of a nice picture of a big house for some reason.

Need some Pics or a link or an Item number to see which one you're talking
about... :-?

Meh. That the way with all diode lasers.

The battery sounds like an 18650

Um... most people consider that a good thing. If it's collimated without adjustable focus, one needs an external lens to burn most things which is a bit of a hassle. You could always move the focal point further away from you until it's focused to infinity and leave it there. That's what collimation IS after all.
