I bought this one over the regular one ( the older model) and oh boy i did not regret my decisions! with the lower profile head you can get to harder to reach places! and there is more torque too. I work at at dealership and this tool is a must have, only issue i have with this is the battery life, being a m12 battery and all you would have to charge it very often if you use it alot. overall great tool! would recommend to anyone who works in automotive industry.
