## Description

From the manufacturer

Review: Excellent - Very good piece of kit
Review: Poor Quality and Poor App. - This is an appalling charger. It doesn’t work. The App is glitched and does not recognise on Bluetooth the unit. Charger refuses to start. The instructions on the App do not solve the problem. It is an expensive unit with poor build quality and which doesn’t work. I’m stuck with mine as too late to return. So a total waste of a lot of money.

## Questions & Answers

**Q: Have a lexus sc430 that do not use a great deal so battery keeps going flat. please confirm i can use this as a trickle charger**
A: I use it for exactly the same reasons.   I don’t use the Benz 63s 2020 for 6months, would go flat in 3-4 weeks with the connected apps etc.  This keeps it low voltage topped up.   Brilliant.
