Personally I don’t think it’s a big issue. Before we had sites like FapTap or SLR, we also downloaded the videos and scripts and played them with the Handy online player. Later we got good community software like ScriptPlayer. FapTap is also pretty new and just a few months old. I think most people still download the video and script and play it locally.
The software for the Syncbot is pretty good. I am not using the Syncbrowser that much, but I think it’s good and offers a cool experience. I mostly use the normal Syncplayer. While it needs more features like better sorting, the software works really well and I never had any issues with it. We also should give the Syncbot team time to develop their software and hardware. It was the same with the Handy. They improved the device so much over time.
If you can afford, go for both. The Handy is a great stroker, that works really well for harder and intense videos. The Syncbot offers a unique feeling with the rotation and contraction and is awesome for slower videos, especially blowjobs / handjobs. Variety is always great and you decide what you want to experience for the day.
I wrote a in depth review about the Syncbot. Maybe it could help you decide if the Syncbot is something for you or not.
