I'd had a couple of the old style "handbag" sized starters and when I saw this I was initially skeptical but after a bit of reading this turns out to be highly regarded.
It's highly regarded for good reason, it works so well!! I've a Renault Megane with a dying battery and with Covid the car hadn't been started in weeks and the battery was flat as a proverbial pancake.
Charged this for a few hours and plugged it on to the battery and left it for a few seconds, car started on the first try. Looking at the charging lights on the NOCO and it was still showing full power.
So small, well packaged, nice little carry case to keep everything tidy. I've no hesitation in recommending this to anyone.
