Shipped literally the next day. Après un été dutilisation je peux dire que ces un très bon produit. You do have to be careful with them when folding and unfolding them but that is literally my only critique. But once I listened, I immediately noticed the organic sound signature coming out of these. The battery life is not as long as the last one I had but it is good enough for a day by the pool. As many others have noted, the difference in comfort is day and night. Not terribly important as I dont especially mind but its almost too bassy. With the help of a friend we started moving the vehicle, then one of the casters bent and the whole dolly came out from under the tire. The side covers do not stay attached very well and these bars do not fit the Yakima bike racks. Im going to break this review into 5 parts.
