AAA Battery Holder Adapter + 18650 Battery Tube Sleeve + Waterproof O Ring for Tactical Flashlight (3 in 1)

I give it a five-star because there is nothing wrong with the product itself. However, it is not the part that I needed. To return this $6.99 item, it would cost me $5 according to their return policy. So it was a waste of money for me. But if it's what you're looking for, it's worth the money.

it fit

Should have gone with the cheaper solutions. The plastic sleeve that I assume should fit over battery holder, doesn’t. Not sure why they even sent it. Therefore the rings are useless too.

Junk

As expected!
