Review on 📱 GUAIMI Motorcycle Magnetic Phone Holder - Fork Stem Mount for GSX-R600, GSX-R750, GSX-R1000, YZF-R1, S1000RR, Kawasaki (16-18mm) by Michael Murphy

I have a 2005 Kawasaki ZX10r and this unit fits perfectly in the center hole of the stem. I doubt the quality of this product. There is a nut that pushes three pieces of metal apart when you turn the hex bolt. My problem is that the part of the nut that touches the metal has a lip so when tightening it never gets past the metal parts that have to come apart to hold the device in place. In my case the nut broke when I tried to tighten it; it never hit three pieces of metal that were supposed to be inside the B-pillar. To thank the seller I immediately requested a replacement and it is on its way. This time, I make sure the nut hits the three fold-out metal pieces before inserting it into its stem. Researching my current device, I noticed that I could use pliers to pull the three metal elements outward so the nut would go through the inlet. Seeing how easily this nut came loose I now know not to apply too much torque when tightening or I'll break the nut again. Apart from this problem I am satisfied with the product.
