Did not work when I received package. The two thumb joysticks have the right tension. Moreover it auto pairs with the last device it was connected to when taken out of the charging case. It makes using the device quite difficult, to say the least. bottom line, I?m keeping them they do the job I need them to do and I travel with them. I may return them. Make sure you measure before applying to the wall! The stock tips are great too, but I use them with the Spinfit SP 145. It is the wood wedge that is from the current Jack Rogers Line. This is not my favorite trainer that Ive ever purchased but it is fine for every day wear.
