The advantages of the laser pointer from the htpow store are its durability/sturdiness and the specificity of the beam width adjustment. I got a 2 star rating for this. Honestly, I expected to be very impressed, but it didn't happen. As a law enforcement officer, I purchased this to put in my personal vehicle, but if it's quality, save money. These high power laser pointer are not as sensitive to shock as incandescent bulbs, but, contrary to the hype, they can be damaged by shock (this is from direct experience, since I was involved in the manufacture of lasers).
First try buying a laser pointer
I decided to try this model. I must say I am impressed! It's small enough to fit in my tool holder and has a very powerful blue laser pointer. The multi-output power switch is a negative for me as it requires multiple clicks per use. So overall happy with how it works when it does work, but it's not reliable nor long lasting. The tail/module buttons don't seem too loud, but I don't have any issues. If it costs much more than that, I might start taking a closer look at other brands. It's also lightweight enough to fit in my back pocket, right next to my purse. Just ordered another one today though! I bought it in December 2015 as it was a Christmas present and when I got back from my family I already got these laser pointers I hate them. They are dropped, bumped and used on and off countless times a day.
