Q: Great book if you bought an air fryer and want some more recipes!I just tried a few recipes, but it's really a good starter book for learning the initial use of your fryer.

A: positive

Q: I never wanted to be a dog parent that needed one of these, but here I am. I have a year old puppy that will not listen when it comes to eating things he's not supposed to outside. It's super easy to use and I love that there are different settings. I mostly use the vibrate but when I do need to use shock I have to use at least 80 for my dog to even notice it. My use of the collar is to have my dog drop whatever is in his mouth from a distance so a lower setting might work for your dog. There's a charge port to put the collar and remote on which is awesome. The collar is also super long but you can trim it to fit.

A: positive

Q: The gears strip too easily. Our first unit stripped after less than 1 minute of play, literally. We decided to replace it, and at least the second unit lasted about two weeks before its gears stripped too. Now we’re returning it (the replacement) for a full refund. UPDATE: about 14 months later (May 2019), we decided to risk getting a *third* one of these. Its gear stripped within 1 week of play. With one bad car, maybe we got a lemon. Two bad cars is very unlikely, but still possible. Three is astronomically unlikely. There is a manufacturing defect somewhere. We’ll be returning the third one and never buying another one of these again. The weird thing is that the other karts in this series (Mario, Bowser, Donkey Kong) don’t have this problem, or at least if they do it doesn’t appear right away (within the first two weeks). We know, because we’ve bought like 10+ of these over the last couple of years. (One of our dogs loves to play with them.) All three of the newer Yoshi models stripped their gears within two weeks, and none of the others did. Something is rotten in the Yoshi production line, something that weirdly doesn’t affect the other racers in the line.
