The product fits correctly, accommodates the rechargeable AA cells properly, and the calculator works well again. The workmanship of the product is excellent.

These holders are a perfect fit. However it is worth noting that you should use **flat-top** AA cells, not the usual type with a button on the positive end. The original HP packs used flat-top cells. They are slightly shorter so the springs compress more, allowing the pack to be removed easily. Using button-top cells both the original packs and the Calculator Store packs are very hard to remove.
