Does this test CR2032, CR2025 and LR44 batteries?

Ken. I looked up those batteries you were asking about. Since I don’t have them, I can’t test them. There is a slot on side of kit for some of these batteries. I just never used it but was having a look at it after my last answer. It’s discreet so barely noticeable. At end of the day this is a fantastic piece of kit and it’s only 20 quid and should be in every household.

Why does this item have a subscribe, does it only last a few months?

The item seems to be durable. As for now I don't have any problem with it. You can just ignore the subscription and buy just once. I think the subscription is to suck more money out of you 🤣

On the front of the battery tester top right can any one tell me what the 2 silver buttons are for please.

They are for testing 9 volt oblong shaped batteries, the ones with the terminals side by side at the top.
