## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent - works perfectly
*by M***T on 28 May 2025*

Excellent robust gadget - an easy fit onto standard battery terminals and connectors. Works perfectly to protect battery from "drains". Great value.

### ⭐⭐⭐⭐⭐ Super easy to fit.
*by A***R on 5 February 2024*

Nice quality units. Very easy to fit, less than five minutes once bonnet is up! Works well, switches on and off easily. Arcs a little when switched on as expected so with prolonged use may need cleaning on contact surfaces. Don’t over-tighten battery terminals or it may snap or damage when fitting. Keep it clean so no electrical tracking can take place which would cause slow discharge of battery. Make sure that there is room for it to fit next to the battery. Only fits on the negative terminal, makes it a little safer for DIY fitters when using a spanner near the battery, -presuming negative ground vehicles! Should increase life of battery as a good battery will only need a top-up charge occasionally. Definitely slows discharge times.Wish I had found these years ago instead of taking the terminal off every time!!

### ⭐⭐⭐⭐ Sticks out a bit
*by A***T on 4 March 2025*

Works as expected, sticks out a bit far and was a squeeze to fit on my Zafira but can be done.Does the job of isolating the battery and reasonable price.
