There is a NEW ice holder in late development. I have installed a set for a tester. I won't post any more info or a picture for fear of breaking MSH rules on releasing info on things that might not supposed to be public knowledge yet. Sorry.
I will say, for those interested, it is a much simpler and easier unit to deal with while still retaining the Marsblade motion offered in the original ice holder (with definite refinement). I was quite impressed with the design...and yes they are far lighter than the 1st Gen.
Great product coming from Per and the folks at Marsblade hopefully soon for all...
