CSL Wireless Vertical Ergonomic Mouse, Bluetooth 4.0 Wireless Optical Mouse TM137U, Mouse without cable 6 Buttons, 1600 dpi, Prevention against mouse arm tennis elbow For PC Laptop Macbook

My order was delivered on time - if anyone hasn’t used this type of mouse before please do so as they are so much better than a normal mouse.The feel in your hand is exceptional, so comfortable. It’s very responsive and not glitchy when operating.Very much recommended.

I previously suffered from rsi pain in my wrist for quite some time, but since changing to use this mouse I do not experience issues anymore.The Bluetooth function works well - I use this with my mac.Really pleased with this product and would not be without it.

The mouse is nice and met the needs of my partner who needed it due to mobility issues. Price was good and the first one last nearly 12 months. It failed completely. No power, no pairing, no lights coming on (even with new batteries).Manufacturer was great and sent another one. This last about 2 weeks and also failed. So looks like they’re not very reliable!

I had spent 4 times the amount I paid for this mouse on a branded ergo mouse - which only aggravated my elbow pain further. I have just started using this mouse and already my wrist sits in a much more comfortable position and the mouse feels super comfortable in my hand. Very easy to set up the bluetooth and seems to be very responsive. Great for the price.

Installation was simple just turn bluetooth on in your pc, insert the batteries and follow the instructions to connected up instantly. Just be aware that there in no bluetooth dongle with the device.

When it worked the mouse was great. I do prefer vertical mice over normal. But this one stopped connecting after a few months. It wouldn't enter BT sync and eventually stopped turning on, despite new batteries.

Connectivity was poor.

I never write reviews, but I had to let you know how good this mouse is.My girlfriend says I have big hands, and maybe its true, because the Logitech Marathon mouse I was using for a couple of months started to feel too small and thus uncomfortable.So I searched for an ergonomic mouse on Amazon and took a punt on this unknown brand because of other positive reviews.So here's another positive review. It's a very nice mouse and feels good quality for the money - comparable to Logitech.I use it with a MacBook Pro and have no connectivity or sleep mode issues.My only gripe, it feels too light after the Logitech Marathon - just got to get used to that!*** Update after a few months ***This mouse hammers the batteries. I use it pretty much 5 days a week for 7 hours or so and turn it off outside of that. I've got through 3 sets of batteries, and this mouse takes 2 x AA, which I think is excessive! So I've dropped it down to 3/5.
