I purchased the NX10 Slope to replace my stolen NX9 Slope thinking, except for the interchangeable skin, they would be very similar. Not so. I was very happy with my NX9 Slope because it was simple to use, provided all the features I needed on the golf course, and was a very good value. The NX10 Slope is very similar in those respects but I find that it acquires the target and provides haptic feedback better and MUCH faster than the NX9 Slope, and the range and slope accuracy are spot on. It seems more solid and, while not heavy, has better heft than the NX9 Slope which makes it more stable in my hands when shooting a target. The case is also better and seems like it will provide better protection if it gets tossed around. And then there is the interchangeable skin and faceplate...this doesn't do anything for the function of the rangefinder but what a fun feature. I just wish the additional skins didn't cost $25....seems like a lot for a fun feature. Anyway, I am extremely happy with the NX10 Slope and it was a great value purchase. I guess having my NX9 Slope stolen was a blessing in disguise. If you are in the market for a rangefinder, I HIGHLY Precision Pro's NX10 Slope Rangefinder! P.S. I added the GOLFTEC Oval G logo sticker myself.
