[EX Q]: A progammable thermostat that you can actually set differently for each of the seven days - perfect for people with non traditional schedules. And the 'off the wall' setting capability makes it very convenient to set up.
[EX A]: Positive

[EX Q]: All the features are nice, TV Guide worked (note that browsing and setting recording preferences is very SLOW), BUT when the TV Guide is downloading (all the time) or you are recording / playing from the hard drive you constantly hear a grinding sound from the hard drive. These guys must have used a cheap hard drive or something. I have the Amazon return slip on my desk......
[EX A]: Negative

[EX Q]: I bought a pair of these to replace similar hoses in my 5'er. The came on time, were well packaged, and work exactly as they should work. I had a tiny leak in one of the originals, and so replaced the pair. Very happy with the results.
[EX A]:
Positive
