I build houses for a living and recently upgraded my cordless tools to the XRP battery model. I wasn't sure if the investment would be worth it or not, but I have been very pleased. This DeWalt 18 V XRP Cordless 9-Tool Combo Kit with Impact Driver set really has most of the tools you would need in carpentry. First, I like that it has two contractor bags with it which is a nice touch. What I didn't like the most is that it only came with tow batteries and one battery charger. Nine tools with only two batteries? That doesn't make sense to me. There should have been at least one more and even another charger would have been nice. Buying them in a kit like this you do get something that maybe you don't really need like the flashlight, but it does make each tool be the best price you may find. I found that I really like the XRP batteries. Not only do they make the tool lighter but they do last considerably longer which is especially useful in my industry. I find that my arms don't tire out as much anymore since the tools that I use all day are lighter. I would definitely recommend buying this tool set!
