Some of the reviewers on Amazon's Website might not agree with you.

There are two reviews of this product claiming significant capacity loss after only a few charge/discharge cycles.
The physical size of the cell might be an issue in some equipment.
Like one reviewer of this product, I have also had problems with some rechargeable cells (not this make) being too large in diameter to fit in one of my torches.
I find the sanyo eneloop a little bigger than a standard AA, and is a little tight for some equipment.
As for performance, I try to look at a broad range of reviews\recommendations, this review is very much on the positive side for Panasonic Pro's, you makes your choices
