Of the Yootech products Ive purchased, this one has to be my favorite! They are just a little too quiet, which isn?t what you want your first impression to be out of the box. We have attached two bikes to the two front slots and then carrier bike seats for infants to the second two slots using the cord that loops through the lower bar to secure these infant seats. NO SON LAS ORIGINALES Y POR EL PRECIO- CALIDAD LAS TUVIMOS QUE DEVOLVER The ease of use and extremely simple setup means that this charger works really well! Any grown man who puts a new pair of boots on and complains about them not being pre-worn in, is actually a woman. They are also comfortable - so comfortable in fact I forgot I had them on. I have purchased a similar style many times so I know what size to buy, these fit to tight. Only thing I can fault are the stickers, I think if your going to do something, do it properly. And i install wheels you can move any location !
