Very hard to review parts I never received! Ordered parts September 18, 2026. Received one half of the order on September 23, 2026. Expected the rest of the shipment in the days to come. Never came. I emailed [****] September 26, 2026, told them I only received a partial order. No response. Sent second email on October 1, 2026. No response. Sent a third email on October 5, 2026 asking for the rest of my shipment or a refund. No response. Today is October13,2026. Still… No response! SCAM!
I will be posting these emails on all of my social media as a warning to others.
It works as advertised!
