Flimsy, unreliable switch - Viridian Weapon Technologies E Series Ruger LCPII Green Laser

The first time I purchased this item I was sent two halves that didn't match. The laser side was supposed to be for a Ruger-57, but was not correct. the non-functioning side was correct! After a couple of go-arounds (Viridian said in their brochure to return defects to them, which I did, but then said they couldn't expedite it because I didn't order from them!!!) I finally got the correct one back and it worked through two on-off cycles, then required taking apart to get to work again. After several cycles of this, the laser switch stop working and I've been unable to get it to work again. The switch is VERY flimsy and unreliable.

Since this was the only laser I could find to fit a Ruger 57, I am up the proverbial creek without a paddle. Total waste of money, would not recommend at all!
