Ta. Nothing really special about them I have a similar shelf unit from another company and it is MUCH better! Very easy to install and look very nice. I lost my ear buds because your case doesnt stay closed! I have an average/average+ wide foot and these felt comfortably roomy (but not loose), which is what I wanted in a travel walking shoe, to accommodate tired or swollen feet. The sound is good and they work good with my blue tooth transmitter. My wife loves this waist trainer, biggest thing for her is, she said it?s comfortable and made of good material. Theyve held up for several months, the soles are intact and the velcro is still gripping. Overall, 10/10 would keyboard again.
