Sound is excellent, well balanced, seems sturdy, decent case, just easy to use. Its kind of sung in the bust area but that is how it is supposed to be so they wont giggle while you workout. I installed it on a 2008 Nissan Sentra (bought a kit that made it easy for me to install) It works great, I have an iPhone XR and the apps work great. I would like to see how the story ends, but prefer not to encourage authors over-charging for their works. I use Starbucks brand decaf espresso beans, ground Turkish grind (very fine, powder-like) and overfill, then tamp with bottom side of furnished scoop with good pressure, then run the handle of scooper across the top to remove grinds so they dont stick to the foil tops. So, well see how it holds up. I measured up 70" from the floor, the bikes were shorter than that and mounted the wall brackets with the mounting bar inside. If I lost this pair I would replace them with the exact same thing as soon as I could. Ive just recieved an unexpected invoice they want £17 customs . It only takes a few minutes to put together.
