I've always had Milwaukee power tools and so far so good. Compared to a snap on 12 volt drill which cost the same as this whole kit with batteries and charger I'd say that would be an easy choice. By the way the Milwaukee drill felt like a better quality tool then the snap on brand.
If you are an AutoTech this kit is a must have in your tool box. Saves you alot of time not having to drag air hose all the time. Drill and ratchet get 5 stars. 3/8 inpact gets 4, lacks power but still works great on small stuff like valve covers, pans etc. and light gets 3, magnet is usless most of the time can't hold the light in one place because of the battery weight and the battery is not that heavy, on/off switch can be confused with the magnet. Other then that its really a great kit to have in the shop or when you doing little side jobs helps you big time! Milwaukee did a good job releasing this kit. Similar kit from MATCO would be around $700 +
