[12 months] The adjustability of the mouse makes it easy to gain comfort and support to your hands.

[12 months] Love this mouse, works great and it's comfortable.

[RF] This may be the first mouse that I have really liked.� Over the years I have used mice, trackballs, pen mice and other pointing tools. They all got the job done, but at the end of the day, they were just another tool.
This mouse is a joy to handle, I have it set up with the largest angle and I have been very surprised just how comfortable it is.� I no longer end the day with sore muscles in my forearm.

[12 months] Son retired from Army, walked away with shoulder pain from 100 lb ruck sacks plus other heavy equipment, and started computer school.......this rollermouse immediately eliminated the end of the 8 hour day shoulder pain he started feeling! Ergonomics is the way to go. Rollermouse Red Plus is the way to go!

[12 months] Best vertical mouse ever.

[12 months] I have been using this model of Rollermouse for over 12 mths - I first started using the type of mouse when my RSI got worse and I could not find a conventional mouse that did not cause my pain after 5 minutes of use. I do a lot of data analysis in SAP and a lot of data entry into SAP. I have recently retired and now needed this same rollermouse for myself at home as I have taken on some part time SAP work that includes a lot of data work. The mouse takes time to get used to but once you get used to it it will save you lots of frustration. The copy, paste and double click functions I use all the time with my work. The mouse is great if you have a big screen like a mac - no more chasing a mouse all over the desk. For me it is well worth the investment - a great mouse. Regards

[RF] I have used this product in my workplace for years. Now that I’m working from home - using a lap top, with external keyboard & mouse. I was getting all sorts of pain in arm, wrist, elbow, etc. in this pandemic, one thing I didn’t heed was pain (and resultant irritability). I bit the bullet and purchase this. It was so easy to assemble and connect. Pain is gone! It takes some getting used to the roller bar ( which you roll and slide like you would a Ramadés mouse). It also has. Quick copy & paste buttons and standard right/left click buttons. Overall a dream! Highly recommended.

[1.9 lb] I had the non plus model of the roller mouse with the smaller wrist rest and this larger version took it to whole new level, I highly recommend!

[1.9 lb] Though not exactly a perfect match with the Ergodox due to the shape of the Ergodox, it is still doable. This is great as my daily driver and has helped take out shoulder and wrist pain.�

Only con is that it's not exactly good for gaming due to the edges being a limiting factor. This is coming from someone who games on a trackball.

But I won't dock a star from the review because of it as I knew it wouldn't really do too well for gaming when I ordered it.�

I have put in an order for the Contour Design Unimouse as well for when I need to game.�

This is the wired version by the way. Wire is pretty long and works well with looping through my desk setup which doesn't have provisions for passing wires through, it's an old desk hacked with a keyboard/mouse drawer. I got the wired one because of bad experiences with wireless keyboard and mice from a decade ago, though of course I'm sure that's unfounded concern on my end with technology being super neat these days. Old habits though.

Looking forward to the Unimouse.

[12 months] This is by far the best mouse I've ever owned, and I've been using it for months. It's extremely adjustable, and if you're able to find it, or if they make a new version, it's important to experiment with the angles. Where I first thought I wanted them is not where they ended up. Now, when I use any other mice, they're pretty much unacceptable. I hope a new one comes out if I ever break this one...I still see this one on contour's website, FYI.
