Works well, largely satisfactory autonomy. A minor complaint for a skate that has taken off after a few weeks of use, but easily replaced with a point of glue.
The 2 types of connection are very useful, you get used to very quickly Bluetooth comfort while keeping the possibility of connecting an older device with the (short) Jack Cable
Hard to beat at this price, especially since I took advantage of free shipping.
A product to be all hands!
