Bought a small booster/battery pack it charged my iPad once with a full charge , then wouldn’t charge again Started my tractor twice then would not start it anymore even though this is a small engine. Took it back to the store they said it would take 4-6 weeks to test it , said they would call me back once complete which they didn’t after 7 weeks I called them. They told me there was nothing wrong with it and they gave it back with glue from stickers or labels over the pack Simply did not do what they advertised it to do and will not refund or credit as they said I has owned it 5 months Absolutely shocking service I will never buy from here again Very disappointed as spent thousands over the years Russell Austin
