Over the years I've bought many items from Edisons.
I purchased a complete battery lawnmower in Sept 2017 through Ebay for $249. I've only charged the battery around 20 times and now it is defunct.
Edisons want to charge me $140 for a new battery, I would have thought a lithium battery would last more than 20 charges.
Given this experience, I definitely won't be buying anything from this company no matter how good the deal is.
