The OMS Power Inflator with angled mouthpiece #BCA-157
True to their reputation, OMS once again produces an inferior product.
Servicing the OMS power inflator is not as easy as other inflators. The metals stems screw directly into Delrin buttons, which are easily stripped. The button stems are thin and cheap that break with minimal corrosion. This renders the entire button assembly useless since the broken stem is cannot be reached. It is not possible to buy replacement parts, so you've got to buy another entire inflator assembly.
All in all, I would avoid OMS. Spend your money on better inflators.
