It worked great at first but as I used it multiple times I noticed that it didn’t hold a charge as long from the last charge. It slowly developed into not holding a charge long enough for 1 minute of use even when the green light was on. Even if you have it plugged in, it still does not have full power and is very slow. I thought this would be a good product but it’s just trash now. I don’t think I will ever buy from this brand again
