Well, first off, this BT is bigger than it looks. If you have small ears that don't stick out from your head, then this might not be the one for you. I found it to feel like if I made a sudden turn with my head, it would fly off.The features on this BT are nice, vibrating alert, and the fact that it's an in-ear BT, but that alone will not make it a 'good' BT if the you have to have this thing within line sight of your phone. I put the phone on the opposite side and I started to hear crackling noise (it's pretty bad when the manual says to keep the phone on the same side you wear the BT), so I guess the manual wasn't joking, so what's the point of having a BT if you have to keep it on the same side. Plus I was getting some echoing effect, and it varied on how bad it got...which got annoying really fast.I ended up returning this(Amazon was great about my return) and ended up getting the Motorola H700. It's alot smaller, lighter, and WAY better. I can wear that and don't hear any echo, or any sort of static. I couldn't believe the range on that BT as well, was able to leave my phone on my desk and walk to other rooms and talk like I was still in the same room....If you're not picky about hearing yourself while talking, and don't mind keeping this on the same side with your phone at all times, then this is the one for you.... make sure you get the one that's being sold from Amazon just in case you need to return it, as I was impressed with how they handled my return...
