Now I have heard something good about Harmony's quality.
I ranted off quickly, but the return rate on Harmony Remotes at certain companies based on a claim of the unit being defective is pretty high. Of the people I know in real life with Harmony remotes, all of them have had to take advantage of the warranty, under which Logitech happily replaced the units. The Harmony One I gave my dad last year failed under warranty, then the refurbished unit failed under warranty, then that replacement stopped charging out of warranty, so we gave up. My neighbor came to me for advice after his fifth Harmony failed in two years. My boss went through three before the current unit kept running for 9 months now. I have two co-workers who got Harmony units as door prized at this year's Christmas party and both have are failed, one has two buttons that don't respond and the other won't hold a charge.
Sorry, I hear more about their poor quality than I do about their ruggedness.
Just the same, they appear to work great and when they don't break, people who use them appear to be extremely happy with them.
