You will want to hear from our customers. But here is my biased 2 cents.
There is absolutely nothing wrong with the HoverflyGIMBAL. Seriously, it works perfectly well. As a matter of fact any lag or bumps you will see using it are your gimbal mechanics. The number one problem I have is Poteniometers and I wish the super fast Savox servos were faster. The HoverflyGIMBAL corrects for slow servos with "advance". I have not had a single problem with any of the many AV200-360 gimbals I have built except having to replace pots and dremel tool down socket heads. It outputs 80,000 steps of resolution on each axis much much faster than the gimbals can react.
At this point we need better gimbals.
The only down side right now is the setup software, which is already really easy, to use needs to be cleaned up. Dan and I are working on that in the next few days.
We have sold hundreds of these and are now OUT OF STOCK. We will have new boards in about 2 weeks. These new boards work directly with Cinestar no-name brand servos.
If you convince me that you really need one now I may be able to rustle one up but as of right now the stock bin is empty.
Everyone I have talked to loves the HoverflyGIMBAL
