What people say about Synergy
Been using Synergy for several years now, and had the occasional problem - usually related to adding new computers with different operating systems - and everytime the Symless support has been exemplary - quick - polite - and solutions found.
Colin Baguley
Amazing product. I've used it for several years on my Linux/Windows machines, and would highly recommend it to anyone who needs to use multiple computers at once.
Alan Guinan
This is the best keyboard / mouse sharing software out there. I have used others and while all of them are less than perfect, I have to rate this one the best.
Scott
I have several development PC's running various OS's and am tired of using KVM's. Synergy is a fantastic solution. I had it working within minutes of purchasing. This is a great tool.
Ted
I have a basic license and run synergy server on my MacBook Pro. I run synergy client on an nvidia tx2 dev board and also on a laptop with mint on ubuntu. Synergy works great. Exactly what I want. The mouse and keyboard work fine, copy-n-paste works fine. It's great.
Peter Leiser
Great software, works a treat across my 6pc's. When I had a problem (it was a Windows error) the support team were very quick to reply to my email and the advice given was second to none. Highly recommended
