Decent, but lacking in quality - one of four D spacers unusable
on August 16, 2011
I have a ton of AA/AAA rechargeables and almost no devices that take anything else, so when I recently got a couple of devices that needed D batteries, I decided to get two sets of these. Buying rechargeable C/D-sized batteries and the appropriate charger is a waste, unless you have devices that drain batteries fast enough to make it worth buying the "real" (and expensive) C/D-sized rechargeables, rather than the cheaper ones that are just basically...a AA rechargeable in a C/D-sized shell!
The C spacers work fine; they're the same length as a AA battery, so there's no need for an extender, thus it's just a plastic clamshell. I imagine they might eventually break at the seam, but they'd still work just fine and safely even if that was the case.
The D spacers are more finicky. As others have pointed out, the metal spacers have a tendency not to stay in place. Of the four D shells I received, one of them had warped plastic and a metal spacer that FLEW right out of the shell the first time I opened it. Even playing around with the plastic shell and bending the metal spacer, I couldn't get it to ever stay in place, and sticking it back in was a pain compared to the other three D shells due to how the plastic was warped.
I ended up returning one set of these and keeping the other, since one of the devices I got it for won't be used much, so I just bought D-sized alkalines for it. I would buy these again if I did need more C or D-sized batteries in something where I was going through batteries more frequently, but not fast enough to bother with C/D rechargeables.
In short, these spacers are cheap, work okay (though quality control is lacking), and seem to be the best option for the price. If you have a device that takes C or D batteries and doesn't drain a ton of power between uses, but does drain batteries fast enough for alkalines to be bad on both the environment and your wallet, then these are a decent option compared to actual rechargeable C/D batteries.
8 Jun 2012 edit: I was looking at these again (while trying to find a new pair of D spacers), and noticed the price went up from $5 to almost $10! I would NOT buy another set at that price...at $5, they're okay, but not for $10.
