Works well enough for the price
Color: Grey
This is definitely the cheapest wireless battery I could find for my rotary machine. Keeping that in mind, it works well enough- however, I've only had it for a month and I already have to wrap it tight to my machine or it will loosen and fall off. The connection isn't very secure & sometimes my machine just stops working. I thought it was going to be a problem for me that the battery's lowest voltage is 6v, but honestly, this battery isn't super powerful so this 6v kind of feels like my old Critical battery's 5v. If you are trying to cut corners on price like I was though, this does the trick just don't expect anything super nice. ... show more
