-------------------

Pros: Its cheap, seems to be well made, good materials, long wires that comes stripped, dot seems to have a good divergence size.

Cons: laser isn't bright, the laser light seems to almost make a flickering type effct when the laser is moved around, not sure why that is. dosn't seem to be adjustable.

Other Thoughts: This laser module does not come with a laser diode, which is what i thought it did, this is probably a fault on my part of my expectations. i was hoping to replace the diode with a DVD one, but being it dosnt have one, its useless for me. 3 dollars wasted - good thing its cheap

Bottomline: good build quality, its cheap, if you need this then buy it it will do its job.

Cons: If you need a lot of precision maybe you should think about another item... maybe if not mounted properly it can become unstable (just a bit, but decisive for precision related projects - just depends on what you are doing and what you are aiming for)

Other Thoughts: Quality of this product makes me want to try out more DIY items. If you're having one very specific precise project in mind maybe you'll need a more powerful or overall better laser, but this can come handy just to test ideas or "what ifs", easy to plug and go.

Bottomline: Overall nice product for DIY projects. For its price you can't go wrong, if it's not fit for one project it will be for another, just try it.

Cons: If you want to drive the diode yourself it can be hard to disassemble.

Other Thoughts: looks real good, Gives a quality impression. Easy to adjust the focus, perhaps to easy. If subjected to a lot of vibration I think a small dab of glue/paint/loctite/whatever will be very helpful in keeping it in place(don't get any on the lens though!!)

Bottomline: Useful little laser module at a good price. Getting a few to play with wont break the bank.

Other Thoughts:

Bottomline: Good bipod for the price, at least compared to bipods in my country. Nevertheless, i still think it could be a little cheaper since its build quality isn?? all that.

Pros: -Works like any other bipod but this system can be attached to rifles that don't support other bipod systems.
-It is very easy to mount and use.

Cons: -When retracting the legs, it sometimes get stuck.
-Also it is a bit hard to push the legs up toward the barrel

Other Thoughts: -This bipod system adds weight to the rifle and makes it much more front heavy.
-Also, if you are like me and want your rifle to look very good, it will take a while for you to mount the bipod on as the mounting system will always be crooked compared to the horizontal of the rifle. Try adjusting each screw by a little until you get an even pressure on both sides.

Bottomline: -If you need a bipod system but your rifle cannot support any other design, buy this one. It works great.
