Pros: Does the job quickly, doesn't take up a lot of space.
Cons: A bit noisy, requires special coin rolls.
It is with a heavy heart, that I will be getting rid of my Money Miser today.
Not because it's not been a good unit, or something I've used quite a bit or been happy to have around the house, but because my grandmother got me a different change jar for Christmas, and well, Gram's gift will come first in a non-life changing decision such as this.
I've owned my money miser for roughly 10 years, though the new models are designed a little sturdier and crisper, the basic functionality remains the same. The money miser is an automatic change sorter - You drop all your extra coinage into the top, it filters through a cool mechanical sorter, and with special wraps, they drop into the apporpriate bank legal coin rolls.
The unit is about a foot tall, and 4-5 inches wide, so it doesn't take up a lot of space. It CAN be a tad noisy, but it does the job relatively quickly. I would say it was effective a vast majority of the time, but you do need to be careful if there are Canadian coins in your collection.
The Money Miser runs on 2 C Batteries, and they last a very long time. Other than the excess noise, I was always happy with it. The coin rolls are easy to use and insert/remove, and for people (especially kids, perhaps) who don't have a chance to run out to the store and drop their change into a "Coinstar" machine (which is what I tend to do these days anyway, even at the 8% fee, I find the convenience is well worth it).
So, especially for kids who are learning to save their pennies, I'd say a Money Miser could be a good way to go. For me, Gram's money jar and Coinstar will be the way I go in the future.
I shall miss you, Money Miser.
