Hitachi 12V Li-Ion Mini Grinder Kit

I like the flexibility of a cordless, smaller grinder, but after 2 or 3 Dremel Mini Mites losing charge-ability in <1 year (and replacement batteries cost near the price of the whole device!), I wasn't sure it was worth it. I bought a corded Dremel but it just wasn't convenient, was loud and awkward in certain situations. I am not a super-heavy user, but a moderate do-it-yourselfer, with various applications for a grinder. One of my uses is dog nail trimming, and the corded Dremel really scared the dogs! After researching alternatives on Amazon, I found the Hitachi had rave reviews, and despite the higher price (after all it is a 12V lithium ion battery WITH a 2-yr battery warranty) I purchased. Love, love, love it! From using to grind dog toe nails, to grinding and cutting metal, this thing is perfect for my needs. The battery is larger, but not awkward or heavy. It is quieter than the corded Dremel. And the light? Wow! I didn't know what I was missing without a light! And this thing really holds a charge, even with sustained high speed use. All I know, is I am impressed by this device and when my Ryobi 18V Lithium ion cordless outfit (drill, saws, etc) dies this time, I am going to explore Hitachi as a replacement.
