I purchased my HT820 from Amazon, in spite of the reviews that said it wasn't comfortable...they were right, but I kept it...the earpiece on one of the sides kept falling off and couldn't be securely reconnected. I returned it for replacement from Amazon and that was a good experience. Two months later, the handsfree didn't operate any longer...I'm not sure whether using it during exercising got some sweat into it or what, but I went back to Amazon for another replacement...ooops, no dice, gotta go to Motorola if outside the 30 day window. Fair enough...Motorola customer service reps, to whom English is definitely a second language, were confused. It took four calls to get the problem clear to them. They sent me a car stereo speaker as replacement. Tried again...sent the headset back, and they lost it...being stoopid, I didn't keep the shipping receipt. So now I'm in the market for another one...you can bet I won't buy Motorola!
