Using this mobile device holder is easy. First, find a suitable place like a toilet compartment or common area to install it on the wall. Make sure to use the provided stainless - steel sheet - metal screws for a secure installation. Once it's up, simply place your mobile device in the cradle. The rubber bands at the back plate and cradle will keep it from sliding out. You can also hang your bag or other items on the integrated hook, but remember it has a weight limit of 300 lbs. When it comes to maintenance, use a mild cleaner to wipe the stainless - steel parts. Avoid using abrasive materials as they might scratch the satin finish. Keep an eye on the set screws and threaded posts to ensure they remain tight for theft resistance.
