When I first discovered BTSync I was bowled over and wowed by its simplicity and ease of use. Version I was an excellent product, with good security and flexibility. Then along comes 2.0 - and with it, a tale of woe and growing disillusionment. To get the shares I needed it was necessary to rig up new devices when I only needed one, just to stop the promiscuous syncing between every folder in site. I eventually gave up because the time and fiddling outweighed the functionality. On the licencing issue, the company has taken a nose-dive into shallow water. Subscription models are not popular with any of my colleagues, friends or contacts - nor with the majority of contributors to this forum. I want to buy a product and upgrade it when needed. For good, fair and successful software licence models you have to look no further than the excellent JRiver Media Center, or my favourite backup system, R-Drive Image. Both of these I've happily upgraded through several major version changes. They've got a happy customer and a regular cash flow from me. I no longer have a syncing feeling - I have a sinking feeling.
