"The story of one of the most prolific, independent, and iconoclastic inventors of this century . . . fascinating."--Scientific American Nikola Tesla (1856-1943), credited as the inspiration for radio, robots, and even radar, has been called the patron saint of modern electricity. Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology. Among Tesla's creations were the channeling of alternating current, fluorescent and neon lighting, wireless telegraphy, and the giant turbines that harnessed the power of Niagara Falls. This essential biography is illustrated with sixteen pages of photographs, including the July 20, 1931, Time magazine cover for an issue celebrating the inventor's career. "Wizard is a truly remarkable biography of a remarkable man. The expression 'ahead of his time' is used too loosely and too often today but in the case of Nikola Tesla 'ahead of his time' barely describes the genius of this man. Marc Seifer makes us understand not only the man but the times in which he lived."--Nelson DeMille "A deep and comprehensive biography of a great engineer of early electrical science--likely to become the definitive biography. Highly recommended."--American Association for the Advancement of Science "Vivid, revelatory . . . the fullest account yet of Tesla as an entrepreneur, experimental physicist and inventor."--Publishers WeeklyBinding Type: Paperback

A shame
Color: Blue, Color: Blue
This product was disappointing, giving 2 stars because it does seem to be a fun toy for dogs; however, within just a day of me giving this to my two 20 pound dogs, they ripped up the top, pulling off shreds of plastic. Luckily this was under supervision so neither of them ate any of the pieces but I could see this easily being a hazard for dogs, especially smaller ones. Whether choking or ingesting, this could be extremely dangerous. Not very good quality.

Must have dog toy!
Size: Extra Small, Style: Bristle Bone
I bought the PetSafe Busy Buddy Treat Ring Variety Pack for our 15 lb Shih Tzu and he absolutely LOVES it. The second he sees me pull it out, he gets so excited. We use it mostly to keep him entertained while we pull our cockatiels out of their cage for the day.
This is such a great toy for mental stimulation and keeping him busy. It’s interactive, keeps him focused, and makes treat time last longer instead of him just inhaling snacks in two seconds.
The rings are extremely durable, they treats fit really well, and it’s nice having a variety pack. It’s also a great option for small dogs who need enrichment without it being too heavy or difficult to use. The rings have no odd smell like other toys do. They come in an array of sizes and this particular one has little bristles that work as a tooth brush while he is using it as well.
Highly recommend if you’re looking for an enrichment toy, treat toy, or something to keep your dog entertained at home especially if you are using it for what we are.

The best safe, chew toy that offers variety and a challenge to keep your dog occupied.
Size: Medium, Style: Bristle Bone
My 60-lb, male Golden Retriever LOVES this bone. My first mistake was I put it together too tight; second mistake I loosened it too much and he had it pulled apart in no time. Now, it's just right. He wasn't sure about it, honestly, for about 5 hours. He is a chewer, he gets bored quickly, he's such a great dog I wanted him to have something indestructible, safe, and allow him different types of chewing in one toy. OH MY GOODNESS! This toy checks all the boxes. I did think I bought a Large; turned out to be a medium which is really perfect, for 50 to 90 lb dogs. And what came with this purchases was a bag of the treat rings. So glad I did! Finding the right chew toy to occupy this adorable boy has been a challenge. PetSafe, you met the challenge! Thank you so much!!

Great to stop Doggie boredom/barking
Size: Extra Small, Style: Bristle Bone
For tiny dogs, these are great ways to entertain the pups and get them to clean their own teeth; I have had one for 5 years and the dogs never were able to harm the white parts. I gave it to a pup that was homeless and I didn't have the heart to take it back later - It is quiet as a mouse and fits perfectly in tiny dog mouths. You do have to have their raw hide inserts but they're easy to find, not expensive, and again is great for boredom time for the dogs.

Favorite chew toy
Size: Medium, Style: Bristle Bone
Pros: this is our dog’s favorite toy. She loves to eat but isn’t much for chewing. At 2 years old, her teeth were already looking pretty bad because she swallows everything whole. That makes most chew toys dangerous. This is the first toy that she chews aggressively. At first we had to give it to her in short spurts because her gums bled. That’s stopped, her teeth and gums look healthier, and she carries it around with or without the inserts. She loves it.
The con: the bristles come apart after aggressive chewing. She swallowed some and I caught the other side coming off.
So whenever I see this on sale, I buy several new ones. I don’t try to make it last and I check it often for damage.
