Review on 🔧 Dremel 7700-1 MultiPro 7.2V Cordless Rotary Tool by Jose Strong

I'm not sure if I received a defective unit or not, but swapping bits in and out of the chuck is quite frustrating. You hold down the blue button to lock the chuck, then use a wrench to loosen the nut a bit, then open the chuck further with a few turns of your hand. My old (corded) Dremel works the same way and I'm already used to it. But after loosening the nut with a wrench and tightening it with your fingers, most often the nut just keeps unscrewing, but the chuck doesn't lose grip on the accessory and the nut just keeps unscrewing until you hold it in your hand again. This means that something in the cartridge/nut assembly is malfunctioning or stuck. What should take 10 seconds to change accessories can end up taking a minute or two if you try to get it to work over and over again (it will eventually work or not. In some cases, you'll literally have to pull the accessory there the chuck won't come loose no matter how loose the compression nut is Also the whole block looks very cheap On the whole these tools are cheap so I guess I should have expected that But from the pictures it looks more solid and 'tall' Quality" than it actually feels in the hand. Overall I like the convenience of the Cordless Dremel (my first) but the quality is way below my years old Corded Dremel. My old Corded Dremel looks like a Volvo and this cheap battery model With a Chevy Vega I will contact the manufacturer and try to get a replacement hoping this one is actually somehow defective with its vise.. never e weakening the grip of any accessory.
