I've only had my Elite a few weeks but my initial impressions that it is a lot faster than my previous 900. Previously, with my 900 , I spent a fair bit of time optimising the various delay settings and found I could improve it quite a bit. For my 861, I reduced the inter-key delay to 100ms from its default value and the number of command repeats down to 0.
