My heel does lift a bit when I walk, thank goodness for straps! Product is durable and very sturdy. This system just works. Usualmente mi celular tarda años (se siente asi porque mi celular me define y al no tenerlo conmigo mi vida se va) en cargar pero este cargador si que funciona rapido! Heartfelt and unique, easy to read (its mostly in conversational style), only 2 characters to worry about, and beautifully elaborating on ethics and humanity. I did the assembling by myself in 30 minutes, the assemble is as easy as the ikea furniture, the manual explains it very well and easy. Build quality is very solid, a bit bottom heavy, with everything where it should be. So if you dont like ear tips I recommend trying these ! Only down fall was some paint was already falling off when I opened it. I wish the legs would make a click when theyre fully open, sometimes I cant tell, but I feel perfectly safe riding.
