these cartridge shaped gadgets are made cheap and fail pretty regularly. Don't buy one, buy three so you have one working when you need it. Great in theory, lousy in actual use. Same goes for the red shotgun shell version.
I prefer this magnetic one made by sightmark, at least as accurate as the chamber things, and more reliable:

Cost is around $50.00. They are best used indoors, like in your basement, after setting up a scope. The tapered magnetic pin is spring loaded and inserts into the barrel as much as it needs to to stay centered and on the gun.
The red is not very visble outdoors (i.e. forget it at 25 yards in sunlight). If you're not careful at the range, you can forget about it and shoot it off the gun.
No, I haven't done that.
Next choice is the wheeler professional laser bore sighter for around $125.00
Spend a little more, be a lot happier.
