I got this back in March07, when it was just released for about $90. At that price I expect this headset to work SOLIDLY. I found out that it's best feature (slider) turned out to be the worst 'feature' due to a hardware/firmware bug.Pros:1) Its a slider, so you can have it on your head, in OFF position (saves battery). When you get a call, press the main big button on the headset, the headset opens, powers up, connects to the cellphone AND picks up the call in about 4 secs. This is GREAT because you can turn on the headset ONLY when talking and its off at other times --> AWESOME battery life.NOTE: You can turn off other moto headsets (eg. H700) between calls and still leverage the great battery life. But those (flip headsets) can't be worn on the ear when off. Only this one (slider) can be worn on the ear even in off position.2) Super fast re-connect times (see above). Most other headsets take so long to re-connect the caller hangs up/goes to voicemail.3) Good battery life, GREAT if you slide close during other times.4) Decent voice qualityCons:1) Ok, this is the 'failure' I was talking about. After 2-3 months, my headset would remain on, even if I slided it shut! Sounds like a small problem but its really annoying because it drains the battery and the call button (main button) on the headset is active. So if I accidently hit that button (eg. headset in pocket, I get into the car) it redials the last number and you don't even have a clue. I tried several things like draining the battery->recharging, closing/opening the slider carefully etc, but it's ALWAYS on now, 24/7. So I control the headset by turning on/off Bluetooth on the phone --> a pain!2) Voice quality slightly poor when headset and cellphone are NOT on the same side (eg. cell in left pocket, headset on right ear). My cell is a Motorola razr and I didn't notice this on my headset (Cardo Systems SCALA 500). BTW, the Scala isn't better than the H800 overall, it's just I never noticed this specific point on the Scala.If Motorola can improve the reliability of their product, this is a great one, 5 stars for sure. But for cutting corners even on a premium product, for poor reliability, I'd give this a 3 stars. Maybe even 2.Right now my headset is due to go back to repairs to Motorola. They've told me it will take 2 days to get a repair number (their systems are down right now), 1 week for me to ship to them, 3-4 weeks to repair, 1 week for shipping back. Totally I'm looking at 5-6 weeks without my headset for no fault of mine. This experience after paying for a premium headset, not a cheap Chinese knock-off.I guess that confirms this to be a 2 star product experience.
