So far works great but can be challenging to connect to ports where I think if not careful, it will break ports. This is my 3rd pair of these. The rack is well worth the money, perfect for home use, if you are looking for professional grade look for something else, I have been using it for about a week, everything is good and sturdy, I needed to get an extra bolt, contacted support and got response right away and shipped to me, great service, no complaint. You can never go wrong with a pair of birks, seriously. But once I realized what I was doing wrong, the rest of it came together easily and quickly. I use this MIC with a PRO MPA II pre-amp made by ART. When they were made in Central Europe, they were high quality and would last a couple of years. Note this are not for the Apple made Beats they have a different cord. The rubber straps tend to cover the corner of my phone screens but its not too much of an issue. This product is exactly what I was looking for ? the size is perfect for all my dumbbells, the width and the depth perfectly fit my space, and the bottom clearance height looks just enough for my future purchase of kettlebells, to be put on the floor, under the rack.
