The two biggest drawbacks are the fact that the wires attached to the earbuds get in the way (they need to produce a retractable model), and Motorola does not sell replaceable cushions for the buds.  I lost one that fit my ear and had to settle for a larger one that kept falling out because I couldn't find replacements anywhere.  The range on this thing is amazing, however, and they are lightweight and sound great.  I am moving on to another Motorola device however because of the aforementioned reasons.  The price has dropped on all of them and I can get a better set for less than I originally paid for these.  Also, I tried my wife's LG set....I liked the vibration feature, but the range is MUCH shorter than the Motorola brands.
