What customers say about "Key Specs"
Dremel 7300-N/8 Cordless Two-Speed Rotary Tool
  • Using it as a coffee frother, every day. The slowest speed is almost too fast. So powerful I only fill our cups 2/3 full and then froth, and it froths right up to the tops of the tall mugs!
  • It works great. I didn't need anything with a super speed on it, and these two speeds are slower and easy to manage when I'm working with delicate glass.
  • It only has 2 speeds but you almost always use the high-speed setting with the slow speed reserved for things like plastic.
  • The low speed works fabulous. Have been using it regularly getting the nals down gradually. Battery life is great considering I leave it running between toes as I reassure the pup and feed him treats.
  • Not very powerful, not alot of torque.
  • The fast speed stopped working about a month after I got this. I've been using it with only slow speed and after just three years, the battery won't hold a charge for more than 8 minutes.
Dremel 7700-1/15 Cordless Rotary Tool Kit
  • This new model is exceptionally quite and can do both dogs nails in minutes. I can run this model on low speed and still cut through nails with ease.
  • Has high and low speed which is also a plus. The slower speed can be used for softer nails and in the early stages of training them to let you grind the nails.
  • The 2 speeds are nice since he lets me do his back feet no problem, I use low speed there and take my time shortening and shaping.
  • The highest speed is probably between low and medium on a corded one however it is perfect for their nails.
  • The Hi and Lo never worked correctly. Now seems to be only one speed and sometimes it will stop or start on its own because the battery doesn't seem to fit tight enough..

What customers say about "Features"
Dremel 7300-N/8 Cordless Two-Speed Rotary Tool
  • Lots of available attachments.The ability to change out accessories with out too much trouble.
  • This one comes with all accessories Incase I find another use for it. I just go to my local ace hardware and buy the heads I need for the dogs nails.
  • Really works very well with a lot of other accessory bits that are available. Can be used for a lot of handyman projects around the house. It drills, cleans buffs and polishes and about anything you can think of, but I repeat use caution on skin. It is not a toy.
  • Accessories do not fit, wrong size collet is in the box. If you have another dremel kit just use the spare collet from that.
  • I bought this product which comes with numerous accessories. None of the accessories that came with my product will fit into the collet that also came with the product so it's useless to me. Really lazy and incompetent packaging.
Dremel 7700-1/15 Cordless Rotary Tool Kit
  • This Dremel works very well. I hadn't used a Dremel before. It took me a bit to figure out how to get the bit I needed attached as its a little different than a basic drill, but it all worked out.
  • Great little tool (comes with quite a number of attachments "in the box"), and furthermore, additional types of tools are available, both on Amazon and down at the local home improvement store.
  • I love that this tool came with so many other attachments and that I'll be able to use the Dremel for other projects. I highly recommend this!
  • You have every possible tip and attachment you could ever need. This is really a fine tool.
  • The resistance behind the speed selector lever is so unbalanced that it hardly ever works to operate it with one finger.

What customers say about "Power"
Dremel 7300-N/8 Cordless Two-Speed Rotary Tool
  • For a battery powered dremel it actually has some good power to it. I've cut and shaved down everything from polymer to metal to doggy nails.
  • Works great, enough power to get job done quickly and battery lasts long enough to get through all four feet.
  • It’s not real quiet but it’s powerful and gets the job done quickly.
  • Cordless battery eventually has problems holding a charge.
  • Eventually you have to keep the battery in the charger all the time in order to use it.
Dremel 7700-1/15 Cordless Rotary Tool Kit
  • The battery on this didn't last nearly as long as I was hoping--- only about 30min, and I'd say not even half of that was at high speed.
  • Good to have the cordless feature and makes it versatile for small jobs around the house
  • Pretty weak on the power. However, to be expected from battery powered tool. The cordless feature is super convenient though.
  • We purchased this due to the cordless feature. This Dremel is wonderful we just wish it included more cutting wheels.
  • It's a dremel - what more can I say - the cordless feature is very convenient
