No, they do not offer any support.
Best support is here on this forum. Did you look at the videos? They shew the basic idea. The danger in using the adapter is theta hard drive is not protected for things that might touch the circuit board. If that bothers you, buy and enclosure that makes things much neater. Costs more, but is a permanent solution for a portable backup box. You can always open the enclosure and insert another hard drive.
Actually, I have two enclosures and two naked adapters. And I have a collection of hard drives I have used. Most of the drives work well on the adapter. But a couple of times I found bad drives that would not work at all.
If you get an adapter or enclosure come back here ans ask questions.
