    The original shipment was damaged by UPS where the boxes and packaging were actually crushed and the wiper rubber damaged. I contacted Radley and they sent a replacement in a couple of days which I put on and they work perfectly. The packaging was secure and the boxes were marked fragile trying to keep UPS on their toes. Great customer service and value. I would absolutely do business with them again.

    La livraison était prévue pour fin novembre 2025. J'ai reçu la pièce début novembre 2025. c'est parfait. Le produit est conforme à ce qui a été commandé. L'emballage pour l'envoi est soigné. Il s'agit d'un epièce origine constructeur, neuve. Bref il n'y a qu'à la monter. Pour conclure vendeur sérieux ; JC

    The switch is a genuine GM part just like the seller's listing, but the USmail was a problem - it passed through Maryland which is a USPS wasteland - delivered 3 days late and I really thought it was going to be lost because tracking was no help - just kept showing it was at the distribution center (for 3 days). I'd strongly suggest that the seller look into using another shipper - it might be worth the effort if stuff starts getting lost.
