Too lazy to drive a lock to he hardware store. 1 day shipping saves the day.

This has happened with each battery Ive tried. They still working and no longer for the device after a few days. You have to pry them out. Trash.

Very good quality at such a price. Happy with this purchase.

Great price

My new ceiling fan remote was missing its battery. Found this pack. One was almost expensive as 4 so looks like a lifetime supply of this oddball type.

As Advertised.

Great value!

Local stores only had an 8-pack or were sold out. This was exactly what I needed.

This battery only lasted 3 months with very light use. It was used in our doorbell, the last battery lasted about 2 years.
