I use Sos ($200) + a grandfathered unlimited endpoint plan ($60 a year).
Performance and reliability have been good. I came from team viewer and logmein and I have been happy with splashtop.
You can get 20% for the first year with a coupon from spiceworks

I think that would stack with my referral code ( I would get $10 if you used it)
If they don't stack just use the spiceworks coupon for $40 off
So you would save something like $16.66 + $36 = $52.66
