## Customer Reviews

### ⭐⭐⭐⭐⭐ LED lamps

Great lamps at the right price

### ⭐⭐⭐⭐⭐ Christmas dec batteries
*by C***. on 19 December 2025*

Used at Christmas in a few decorations and all seems good

### ⭐⭐⭐⭐⭐ Good value for money
*by T***R on 27 March 2021*

I have only used one bulb which has been operable for a very short period of time so difficult to comment on Longevity. Value for money will depend on how long the bulbs last, but based on what I paid for the bulbs my initial perception is that they are good value for money.
