Review on Bestem BT 3DRSOLO KNOB8 Precision Quadcopter Controllers by Anthony Watkins

I don't quite understand all the 5 star reviews for this product. The pens are ok and I'm sure they will do the trick but for $14-15 they are terrible. The quality is pretty bad. The set I received is missing the white bits on parts of both grips and the material they are made from (silicone I believe) is the quality you would find in a really cheap thin phone case. If they were around $5 I can understand the 4-5 star reviews but they are DEFINITELY NOT worth $14.
