Love this tool!
I've used the bullet for a few years now. Compact tool and gets maximum torque for your gear. If all you care about is bulkiness, I would go with the Burton EST tool. If you're worried about durability don't ... I work in the oil and gas industry in Alberta and ordered 30 of these for the guys I work with because of functionality in cold weather and how compact it is. All I have received is positive reviews!
