For $30 it's a great little device, decent range, just don't expect to be able to use it in a dark HT environment (at least not as far as the keyboard goes). The trackball is very loose and takes some getting use to, I used one for about a week in my HT and returned it but at $30 I may order another one as a secondary control in my media room.

* Ordered one for $32 shipped, not too shabby, thanks for the heads up CajunCanuck
** Something to keep in mind is that their processing/shipping appears to be pretty slow, my estimated ship date is 8/12 after ordering on 8/5 (so even though it said allow up to 5 days for processing and shipping, before I placed the order, they are actually estimating up to 7 days after the order had been placed). Then their free shipping is up to another 5 days added onto that. Not complaining at this price, just a warning, don't be in a rush for it
*** My order shipped on Monday 8-9-2010 and is to be delivered on 8-12-2010, it does say signature required (so something else to watch for).
**** As of 8-10-2010 the code is still working (just a heads up).
