Blacksuit Car Steering Wheel One-Touch Foldable Knob Leather Power Handle Spinner Suicide Accessory Knob for Car Vehicle Truck

Works as advertised.

Doesn’t lock in down position. Easily slides around, unless you tighten to the point of deforming the bracket. Then knob it to close to steering wheel and pinches fingers.

I've tried a few of these wheel spinners suicide knobs out and this one is the best. It's got the best hardware to secure it to the wheel so it doesn't ever really get any looser on the wheel, but does take a lug nut type of wrench to secure it. Also, the material on this feels great and is large enough that I don't feel any strain after hours of using it. I'd buy it again, but I won't need to for many years. A+!
