I bought 2 of these and have used one of them daily for about a month. I am retired so I tinker with a lot of things using this tool many times a day. One of the kits the battery dead right out of the box, the other lucky works so it's getting a lot of use have to charge it at times 2 to 4 times a day. Tool itself works awesome I live in Tucson Az and the heat here, let's just say I miss Las Vegas lol. It is hot as H... outside the tool holds up it gets hot yet keeps going. I do a lot of cutting and grinding metal and wood mostly. I have not used the other tool yet. But the batteries and the chargers are bad, lucky had another charger from another brand that worked so I had to alter the one to get it to work and charge but didn't have time to send back for a replacement. The accessories come in a bag and most all were broken, chipped, damaged so definitely needs to revise how those are put in. Would give those and the battery a 1 star the tool 4 stars for the price can't beat it. I am hard on tools I always give them a run for the money. Retired construction worker.
