Product quality is good, but the size is too small. In the product description it states it is able to hold an inner tube, tire levers, CO2 canister and puncture repair kit. It was almost full with a packet of tissues, set of keys and energy bar.

Fits well to my bike saddle using the velcro straps. Light weight and water proof. Enough room inside for 2 inner tubes, set of 3 tyre levers and a puncture repair kit. Great value.
Really roomy bag and great value. It looks stylish and compact but I've been able to fit a surprising amount in: 2 inner tubes, 2 levers, multi-tool, 2 CO2, and a mini pump. My only gripe is that the velcro strap which attaches to the seat post hasn't been attached in the middle of the bag meaning that it isn't possible to get it to sit straight. Not sure if this is a general issue or just a problem with my particular one.
Excellent product at a very good price. Fits in a spare inner tubes, tool and tyre leavers. With all fitting snug inside and the adjustable straps connecting well to the seat i’ve ex no rattles or noises.
Bag great and able to carry a spare tube,repair kit,levers,multi tool and gas cylinder, I am at a loss though as to why I was cared 10p for a PAPER BAG the 5p charge is for plastic so who gets this money??? Thinking twice now about any future purchases from there.
Used on tour of Flanders and had holes in it at end of ride. A good price but I expected it to last more than one ride.

Bolsa de sillin muy comoda para uso ocasional o diario.
Ideal para llevar una cámara de repuesto para cuando sales
no es muy grande, pero es resistente y pequeño y no molesta. buen precio.
Le he usado ya por varios meses y estoy contento con él. No tiene una gran capacidad pero alcanza para lo justo. Lo que llevo en él y va a tope es lo siguiente: una camara de repuesto, las llaves plasticas para quitar la cubierta, una mutiherramienta, un par de monedas de 1€, un adaptador de valvula presta por si debo ponerle aire en una gasolinera, las llaves de casa o del coche. Queda un poco de espacio para poner algunas tarjetas y billetes plegados, aunque llevo todo eso en la cartera dentro de un bolsillo del maillot. Hay un modelo un poco mas grande por 1€ mas pero este calza perfectamente bajo el sillin. Si quieres llevar masomenos lo que he detallado arriba lo recomiendo sin lugar a dudas.
Justo lo que necesito, práctico, cómodo y excelente en calidad-precio!!
Esta muy practica
Se acopla muy bien bajo el sillín y caben dos camaras, una mini multi-herramienta y dos palancas de cubierta.
