The best thing about reliabackup service provided by them was their support team, which helped me in every way possible during my entire experience with this product as well its free version too! I have no complaints at all regarding any aspect of it so far; everything has been just perfect for us till now (except maybe pricing). We are using Backup & Sync from last one year or more but we were facing some issues then like slow data sync speed etc., So when i got chance read reviews related to other products also they had mentioned same problems faced while working earlier versions before 1st April 2015 only!! And after reading those comments decided go ahead try out new features offered here instead wasting time searching something else again.
