I've had the cxs since it's release here in Canada, and have pushed and pushed this drill. I took it in for servicing recently but it still feels like it's lost its spunk. It's well outlasted any drill I've owned in it's class by 3 times over at least. To me, the ergonomics are perfect, I really don't see why anyone would opt for the txs instead. while I love this drill and my t 15, my biggest gripe is centrotec. The more stability claim is bunk as I've used very stable standard ball detent bits and chucks in the past and the difference between the two is price and availability. Long story short, the ergonomics and adaptability of the cxs are really something special. Downsides centrotec, and price. Now I'm not one to cheap out when it's the right tool for the job, but I mention price when there are less expensive drills in this class some with higher torque and longer lasting batteries. None with the same awesome ergonomics though.
