Tackform is the best. I love the sturdiness and quality of their parts. I have bought quite a few items from so far for my phone, GoPro and Garmin GPS. I use them on both my BMW K1600 and FJR 1300. I love the quality. And, their support...amazing. I haven't needed it yet for any problems, only for trying to figure out the best way to set my bike up.
