| These truly are an incredible feat of engineering. When my HP calculator ceased to function I was told I needed some new 'batteries' to get it to work again. Apparently the answers to all my compational questions are stored in these little guys, and I had used up all the answers from the set included with the calculator. First I was enraged that I was tricked into buying into a subscription service to use my calculator, I can't just own it, no, I have to pay money every year to use it, and recharge the 'answer juice'. Truly a crock. Then came fear as I wondered whether the new answers stored in the batteries would be as accurate as the ones before, just the daunting prospect of having to test all the possibilities and verify their results sent chills down my spine. But I needed my answers! So I shelled out the money and bought myself four of these magical answer stores. Of course my calculator only needed three (yet another scam from the hotdog and hotdog bun people!), but so far all the answers I've been getting seem accurate, so I give these 5 stars. My only complaint would be that they should be designed so that I can input answers into the batteries myself, so that I might recharge them without buying new ones. This seems like an obvious idea, and I suspect the 'powers that be' are just keeping that technology away so we keep sustaining them with the ridiculous subscription model. | .jpg)
