"These are great. Very reliable!

"I have six of these now. They work great and they are a bit lighter than the all metal ones which is nice when carrying a bunch of them around. I've used all six of them a bunch of times and I haven't had any issues with them. Really happy with this product.

I have had to re-lube them a couple times. When you take them apart there's a good chance that the ball bearings will fall out of the holes in the central cylinder. Put a bit of heavy body silicon grease in the hole, pop the ball bearing back in there and the grease will hold it in place. You'll also want to lube the O ring on the outer cylinder.

Pros:
Great price for the 3 pack.
Light weight.
Easy to reset after each firing.

Cons:
The ball bearings will fall out when you take them apart to lube them. Not really an issue as long as you don't lose them.
