*by M***T on Reviewed in the United Kingdom on 9 May 2020*

Excellent, 1st delivery had a faulty panel, replacement sent out before I could return the faulty one! Great service. Replacement works as expected keeping my boat batteries topped up while out of use during lockdown.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Working even when cloudy
  

*by L***N on Reviewed in the United Kingdom on 13 January 2022*

It seems to be working it shows as charging even on the gloomy days we have had since purchase. It has not taken the battery up to full charge but considering the car is being used daily for short journeys it does seem to be helping maintain the battery at a useable level.It's plugged into an outlet in the rear of the car that is live when the ignition is off, we purchased the lead for this.  The unit is well made and quite big but it fits on the dash still.
