So smooth and easy, so much better than my keyboard that came with my computer. Easy on my wrists also. Well worth the price!!!Great productTried this product because my doctor said my wrists and hands are overwhelmed, and I should try some more ergonomic options in order to help my issue. The potential is there for this product, but it JUST misses the mark for me. The keyboard is thin, along with the attachable padding. The padding does enough to keep my wrists straight. However, the keyboard itself is supposed to curve, and it’s pretty much the same as any other keyboard in that area. There is a very small, almost nonexistent curve or hump between the RTY-CVB area. If using this as a preventative measure, this may be perfect ergonomically, but as someone that needs as much assistance as possible, there could be more of a curve and separation. Aside from that, the keys are soft to touch and very quiet. The mouse runs very smoothly, and the side buttons are a nice touch. Getting both for the price is worth it to me.The ProtoArc keyboard is ergonomically designed with a "hump" in the middle to reduce hand stress. It has good positive key responses with a solid-sounding response when the keys are hit. It is rechargeable using a USB cord and goes surprisingly long between charges. All of the function keys work well on my MacBook. It has an "on/off" button to conserve charges but I find the auto power save mode is just as effective for overnight without turning of the keyboard. Two large orange keys allow changing the keyboard between Mac and Windows with a single button once the dongle is operational in the correct PC.The accompanying mouse is also an ergonomic design but most comfortable for right-handed users. It has two large buttons on each side, a "roller" and a small "orange" button on the top, plus three small buttons on the left side. These buttons are programmable depending upon your application. Again is is rechargeable using the supplied USB cord, has an "on/off" switch and automatically enters a slumber state to save charge life. Mouse response is fast and the size might be too large for smaller handed users.Overall, these are a good combination that should not take long to adapt your typing style to using.Its a bit smaller than most ergonomic keyboards. If you have small hands, then this will work for you. It is nice that it is wireless and rechargeable. It hasn’t lost connection once since I have been using it. It doesn’t have that much of a curve, but then again, I do have average size hands, so I will be switching back to my other keyboard. The mouse is just a normal mouse, it isn't any more ergonomic than an average mouse. In all for $50 bucks it’s just ok, again if you do not have smaller than average size hands, you will want to find something else.Very comfortable feel to this and the special keys were pretty easy to figure out. At first the arc in the center kind of annoyed me, but I got used to it pretty quick and now rather prefer it.These both are very comfortable on the hands and wrist. They are very convenient and east to store and travel with. The wrist pad is very good as well.The keys are very soft to the touch and the mouse works well. I like that they are using the same USB to save on USB ports.The battery has been so far very good and I overall really like this set.The keys have a nice feel them. Both the keyboard and mouse have good response with no noticeable lag. Typing is very comfortable. The multimedia and other special function buttons work (using this on a Windows computer). Installation and setup was a very easy plug and play. If I'm going to be nitpicky, the wrist rest has a cheap feel to it. However, it is soft and very comfortable. Overall this is a very good keyboard and mouse combo. The quality and feel are a step or two up compared with those very cheap keyboard and mouse combos.
