Now, Im not the real benchmark. Would have kept them if I known that and layed them on a shelf. The top screw bears all the weight. Models tried thus far. The warranty is not applicable here, unless bought directly through Bose and not Amazon (found that out the hard way of emails). Does not feel flimsy at all. It doesnt seem to serve any purpose. Keyboard is heaven, processor is fast enough for the most part, other than Catalina its great. This fits perfectly in the Makita case. That being said, it does work, and it is nice enough.
