Review on SHENG XIN Cordless Pre Motor Replacement by Antoine Cash

Worked well enough when I first put them in my Vertex Cordless Shark because I only used a shaker stick. However, as soon as I put the floor nozzle on, the motor started making an awful noise and the vacuum didn't pick up anything. These things interfere with vacuuming so much that I can't vacuum the floor without risking the motor blowing out until I order a genuine Shark product. Be careful.
