### ⭐⭐⭐⭐⭐ Great
*by C***E on 4 September 2020*

Great item & great price. Just what I was after, thanks

### ⭐ Red light won't go off and update and 2nd update
*by P***H on 12 September 2022*

As I can not get in touch with seller through amazon , I will say it on here , the red light should only come on when leisure battery is charging , but it as now been on for 4 days, I'm worried it will flatten my engine battery.UPDATE in bed for 8 days I'll, and the battery on my brand new van is dead red light still on , on the split charge unit and never turned itself off,I have now disconnected the split charge and will replace it with a different make.£65.88 wasted, on a faulty product.Update 2 the leisure battery is also flat but completely, no load on either battery for the 8 days. Luckily I think I am managing to recover the van battery.
