Does the job

Battery pack was delivered quickly and the product is working fine. I only needed one, but bought a pack of two so I had a spare for replacement.However, I couldn't see a use by date on the packet - and only found one by peeling back a label somebody had slyly applied on the back,which revealed October 2025. That's only a little over a year, and the dead battery I replaced lasted more than five years...go figure. This must be old stock.

Fantastic!!!I could not believe they packed a whole 12, Yes 12!!! volts into such a small item and not only that there were TWO of them!!!Despite the lack of clear instructions I was able to install this product which I purchased as a direct replacement for the previous one and I must say I was absolutely gobsmacked at the performance increase on the previous one, I pressed the doorbell and my world was instantly transformed into an audio extravaganza not only did my doorbell go "ding" but it added a "dong" which in my humble opinion is a full 100% improvement on the simple "ding". I have tested this product extensively since I eagerly received it in all of its blister packed majesty and I can state without fear of contradiction that not once in all of this time have I had a single missed "dong", every single instance has been met with a resounding "ding dong". to say that this product is a life changer is an understatement. would gladly have paid ten times the asking price for such amazing service.
