Has anyone tried these battery packs ?

I bought one of Bob's adaptors two years ago and was fully satisfied - it's maybe not quite as neat looking as the website photos but the difference is marginal and in no way affects serviceability. It enabled me to use normal AAs in an HP35, and I've been powering it that way ever since. He replied quickly to my initial e-mail enquiry, and dispatched the adapter within a week of me placing the order - it took a further two weeks to reach me, but that was down to transatlantic transit and UK customs clearance.
