The B-52 Driver upgrade is for those who own the B-52 BUFF Exterior.

The B-52 Driver upgrade is an exact copy of the B-52 Driver but with €10 discount.

We are pleased to offer €10 discount to our most loyal customers who have purchased the B-52 BUFF Exterior model* before the B-52 Driver release.

* - B-52 BUFF Exterior model is currently discontinued.

Hope this helps.
