Good product and a good price
Size: 26"+24"+14"
Fit like a charm and at a great price. The connection points are tight on the wiper arms and the rubber seems to be good quality. Time will tell once these are used for a while to see how they hold up.

Here is a simple solution to replacing your wipers. It your vehicle sits out in the weather, they need to be replaced a couple of times every year or you will be like the guy driving down the highway at 30 MPH in a downpour because they can't see the road. Forget the frustration of trying to look up your wipers in the store that doesn't have the up to date book and get all three wipers for your car here. Also they are a perfect fit and delivered to your home. You will have to install them.
