Review: Great value - Great value for money and they last as they should!
Review: Wait... check first. - These nowadays batteries are child safe and as soon as put it in my Aufi key fob, it would not work. So I very lightly sanded the edges, this creates a better connection and removes the protection layer designed for kids protection so they don't get harmed if they put it in their mouth. Works a treat now.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great value
*by C***M on 4 January 2026*

Great value for money and they last as they should!

### ⭐⭐⭐⭐⭐ Wait... check first.
*by M***H on 14 December 2024*

These nowadays batteries are child safe and as soon as put it in my Aufi key fob, it would not work. So I very lightly sanded the edges, this creates a better connection and removes the protection layer designed for kids protection so they don't get harmed if they put it in their mouth. Works a treat now.

### ⭐⭐⭐⭐ Cheap but 2/5 dead within a month of buying!!
*by M***G on 12 August 2025*

Purchased on 10 July 2025 for use with the remotes than open and shut my sky windows in my kitchen. Delivery was quick and the price very reasonable. Unfortunately just over a month since buying them - and max 10 uses - 2 batteries are now completely dead. Disappointing but I guess I got what I paid for !! Update: seller contacted me unprompted and provided a full refund. Excellent service so back to 4 * review!@
