What are y'alls experiences with bullet vibrators? I got mine from spencers (battery) and less than 2 months later it would only last maybe 5 seconds before dying. I changed the batteries multiple times I know that's not the problem.

I got a new vibrator but it doesn't have anywhere near the same intensity and I loved the bullet.

Is it common for Bullet vibrators to just break like that? Or stuff from Spencers maybe? I want to get a new vibrator that has a high intensity but I'm not sure if I should go to the same place/get the same product.
