We received the mirror we ordered in good condition, but unfortunately it did not improve the visibility of the blind spot at our intersection.
We returned it for a refund as directed, but have never received this even after multiple unreturned phone calls and emails.
The product is good but costumer service is not. Would be cautious for this reason.
We used the mirror for an intersection at our construction project to assist with a blind spot created due to work activity. The mirror worked out perfectly.
