I love the design also in this version

I have been working for many years exclusively with the Logitech Trackman and was delighted that the design has been adopted for the M570er. With a little practice you appreciate the ergonomic design and very noticed how cumbersome and tiring to work with conventional mice really is. I was thrilled when I discovered that the tiny Unifyer has replaced the somewhat unwieldy receiver. Unfortunately the Unifyer stopped working after a few weeks and request a replacement was clearly too expensive. I have now, fortunately, a new Unifyer running properly by dazugekaufete keyboard on both devices. Hopefully longer than the first try! That's why getting the trackball only 3 out of 5 stars. I love the design but I hope that a replacement for the Unifyer offered soon simpler, faster and more cost-effective. Because without this little thing, nothing works!
