2-in-1 Universal Cup Holder with Phone Mount for Stroller Bike Wheelchair Walker Scooter - Adjustable 360° Clamp 1.4-4.5cm Fit Most Phones & Bottles Spill-Proof Non-Slip ABS Plastic

this is better than the other one I purchase some months ago. the one I had before would turn and spill my drinks and drop my cell phone. but this right here is well designed to prevent that. I know it is for bicycles another means but I use it for my electric wheelchair. and common sense makes it easy to install and put forth the item together.
