My major gripe is that with the proper sized earpiece, the unit rotates so that it hangs straight down making my voice muffled to the other party. Adding the optional ear loop works OK but this setup tends to fall apart very easily. I think the reality is that for good stability you need the ear loop, but again, the thing tends to fall apart too easily (not break mind you but the earpiece falls off allowing the ear loop to also fall off). I will look for a more stable solution in the future. Customer Rating: Summary: First blue tooth ear piece, and its a good one! Comment: This blue tooth headpiece works great with my Samsung SCH-u740 (dual flip phone). The only issues I have is that it's battery life doesn't seem to be as long as I would like, and sometimes the reception is a little raspy. But all in all i would recommend it. Customer Rating: Summary: Good enough Comment: The headset works fine... The only thing that I find annoying is the recharger that it gets placed into. It doesn't seat firmly and could be improved. Customer Rating: Summary: the best Comment: this headset is the best. it's lightweight enough to not even notice it. the sound is great. HOWEVER, do not try using it with a treo 680. you'll regret it. but with an iPhone - stellar. Customer Rating: Summary: I loved it, but would not invest in one again. Comment: I purchased two of these discovery 2 years ago and after a month had to send one in for repair, it wouldn't take a charge. It was replaced and I've used it up until a couple of weeks ago, again it won't take a charge. The other one I purchased two years ago went out after about a year and yes it wouldn't take a charge. I really like the size and quality of the volume, its trendy and small for traveling, unlike the other bulky bluetooths available. I would have to say if you buy one and plan on using it for a few years take out an extended warranty, otherwise you will end up in the same situation as myself.
