Input:
Question: Is the charger bi-volt or only 110v?? (I need to use it in 220v).
Document: Instead I've taken the 7700 back to Lowes and I bought theDremel 8000-03 10.8-Volt Lithium Ion Cordless Rotary Toolfrom Amazon which, though almost twice the price, should be sufficient for what I need. I also bought an extra battery for the 8000 in case I need it, which I probably will.Another problem with the 7700 battery is that it's a NiCd (pronounced nai-cad) which is essentially 1980s technology.
I've been using a cordless Dremel for years and the one I had finally died. This new one is better and the charger blinks while charging which the old charger didn't blink so you never knew when the battery was actually charged. Since I have older batteries that  are still good I can charge them and know which ones need charging.
Oh well. As for actual use, it's strong and loud. This grinds down large dog nails quite quickly, and I will not use it for small dogs. I'd get the Mini Mite 4.8 volt one if you're not confident in your nail grinding skills or if you're looking to use it on small dogs.
I use this tool to trim my dogs nails. Makes trimming their nail easy, the tool fits in your hand very well and is light. The charger is fast and easy to use. I would recommend this tool to anyone for a trimming their dogs nails.
Cheaper quality than my old one(2001 or so).The plastic is thin and cheap.The battery would not stay in the charger so I had to use the Dremel tool itself to fix the battery charger so that it would accept the battery into its bay. It works now but it is still not a tight fit.As for the positives, the Dremel Tool works as it should.
The first time I used this item it worked great. When I tried to use it about a month later it was dead. I plugged the battery into the charger and the light was green like it was charged, but when I attached it to the dremel it lasted for about 2 seconds. I'm not sure if the problem is the battery or the charger, but I have tried it in several different outlets with no luck!
Wish I would've gotten a heavier duty one. But this is ok for small craft things. Or maybe I need a class on how to use this.
If you are not an expert pet groomer than I would recommend buying a Dremel that is less powerful. All the professional groomers use this so I bought it. But I need to practice on something that is not my pet dog.
If you are going to perform small tasks, this Dremel is the tool that you would need and use constantly. It provided a much needed sollution to the task at hand! I highly recommend this model and versatile tool.
I use this Dremel, with the regular grit sand paper to file dogs nails in my grooming salon on a daily basis. It works really well for that, I haven't used any of the other attatchments. Overall works great for what I need it for.
