Died after 15 minutes of use - Carson StarMap Astronomy Low Light

Got dim after 10 minutes of use, died completely after 15 minutes. Went to replace the batteries and found them to be special LR44 ones (not a standard AA or AAA). Bought new ones $$$ and light still doesn't work. Bummer. You get what you pay for (sometimes less).
Pros: cheap, really cheap
Cons: non-standard batteries, flimsy construction
