    There is no clarity in the lenses, you connect the phone with rubber bands and suction cups, resulting in the inability to focus the phone's lens with the telescope lens. The tripod is not stable, we are afraid to move it in case it breaks. Unfortunately, I am disappointed with the purchase of this particular model. It's a shame because I got it with joy.
