I upgraded to the Hamskea earlier this summer. It is worth the money. Very smooth operation, the double bearings make a difference. Versatile in configuration/set up. It really is built like a tank, it is not going to break. I bought the full containment model figuring I could take the top part off if I didn't like it there.
The rest, like any limb driven model, is very easy to set up. Put your bow in a vice so it is level horizontal and vertical, then bolt the rest on level. I use the limb attachment system with Halo cord and like that configuration. Some don't like this and just tie directly to the limb, yoke or axle with D loop cord. The limb attachment spring will eliminate any bounce back of the rest arm. It is quieter than both the original Limbdriver and the Limbdriver Pro V.
Mine survived my yearly backcountry elk hunt. No issues at all. It is a very solid rest construction wise and I never worried about it. Much better rest than the Limbdriver that it replaced. Not even in the same league.
Some things to consider with this rest as I did have some problems with it initially.
It will come with a little rubber arrow shelf on the back of the rest body, take this off if you use high profile vanes like Blazer's. When I first set up and shot mine it was actually stripping the fletching off of my arrows when I shot them. I posted about this on Archery Talk and several had contact issues with the rubber block. Even after the block came off I was getting vane contact. This was with a Bowtech CPXL. I emailed Hamskea and they said they would send me out a different rest arm right away, I get the feeling there have been clearance issues in the way that they handled this. It didn't help and no matter what I did with the Bowtech I had vane contact.
Ended up buying an Element this summer and have not had contact issues with it on this bow.
As was mentioned, this is a bulky rest and can cause some issues. If you use a tight spot quiver you may get contact with the rest, again with a Bowtech this seems to be an issue. It works, just barely with my Hoyt and a tight spot. It is a bulky enough rest it may limit quiver options and orientations. With the containment cage on you will not get clearance between the rubber damper on the Bowtch Flexgaurd. It didn't seem to make any noise with the rubber resting against the cage but this may bother some people. The cage is big and the full containment rest arm is wide. It will not drop very far on bows with narrow, curved shelves, both Bowtech and Hoyt. The rest needs to be mounted far enough back that the arm is completely behind the shelf when in the down position. On a Hoyt riser this will have it mm's from contacting the riser bridge.
They also need to machine more position marks on the vertical adjustment bars. Set up on the Element, dead level with arrow bisecting the Berger hole the rest is on the last lower machined mark. If you you need to lower the rest for tuning purposes there would be no point of reference for moving it. The rest arm itself is appears short, this is where the contact issues come in. When posting on AT, take it with a grain of salt, had several message me that they had contact/clearance issues they could not get resolved and ended up selling the rest because of this. I don't think they had Blazer type vanes in mind with their tolerances when they designed this thing.
I'm going to keep the rest and again, I do think it was worth the price tag, but there are some issues to consider.
