The wire that connects to the actual earbud feels pretty thin and frail. These trainers are so comfortable and light. Good value for money. Ive had no problems at all. The last and 2nd flaw has nothing to do with the mouse per-say but the software. Does anyone have suggestions on getting rid of it? I like the sandals. Filled all the jars and put the stand on the counter and it has held up against 3 kids and a husband using them. Beautiful heels, but it?s very small, order two size up! Three 6-Quart is even more wider than the 28-Quart. I cannot say enough good about these.
