The tool itself is really good IF the included charger works. The charger worked once to charge the battery first but never worked again. Usually when something goes wrong the first thing that comes to mind is the battery so I bought another one. Same problem - the charger should blink while the battery is charging and then stay on when the battery is fully charged. With both the original battery and the replacement battery, the charger will blink twice and then stay on and not charging, meaning you cannot use your Dremel. I then did some research online and found on Dremel's own website that it was clearly a charger issue - numerous replacement chargers in the reviews section with an overall rating of 2.5 stars. Buyer Warning.
