I no longer buy any accessories for a GPS (or cell phone accessories or other tech accessories)directly from the retail shop where I've purchased these items, as Amazon offers these accessories at a much better price and the Generic versions I've purchased are excellent and reliable - in this case, a charger for my Garmin NUVI 1490T.  Very happy with my purchase.  I've had the item for over 2 years now and it still charges perfectly.  Trust Amazon's sellers on items like this.
