See a whole new world
on August 9, 2009
I use this for checking gold ore samples in the field as well as general looking at the microscopic world.
The LED light is great but I did have one problem. I left it on and the next time I tried to use it the light would not work.... dead batteries. Unfortunately the batteries cost near $5 each times 3= $15.
All is not lost however. The Rite Aid (Pharmacy) had hearing aid batteries that, while not the same type as the listed required batteries, were the same physical size but were 1.4 volts instead of 1.5. I did not feel that this would be an issue and decided to try it. They worked just fine and were $16 for 24 of them, so about $.67 each. Much better and I now have 8 changes in case I forget to turn it off again.
The replacement type I found was Size 312, hearing aid batteries.
