No-Load/One-Wheel Syndrome
A common misconception is that a Torsen-Style Differential is useless under a no-load situation (e.g One wheel in the air). Although true to an extent, this no-load situation does not apply to the modern day car with Traction Control (or eDiff). For those without traction control, there is a very commonly used solution to the problem (used by professional race car drivers over the past 30+ years) that our competitors will not tell you; simply left-foot brake

Exceeded expectations!
Size: Mini Size
This ball launcher has been the best thing we ever bought. We have a golden retriever who of course, like most goldens, is ball obsessed. I have thrown my fair share. I decided to see if my golden was smart enough to use this so we pulled the trigger. It took 3 days of on an off training and BAM! We are in business! This launcher has been a CHAMP! We've had it a month now and it has survived over and over of constant use. The balls are covered in pure slobber and nastiness but the machine keeps going. We do keep it plugged in and only use it indoors. Sometimes the ball does get stuck but it's easy to push it back through. The only complaint I have, and it's no fault to the company, but we are already on our 2nd pack of replacement balls. Honestly, it's been worth it. I probably should have purchased the bigger size but I didn't want to invest in it if he wouldn't use it. Definitely regretting it now!

Best system ever !!
My 12 yr. old Toy Poodle was already trained to a 'piddle pad' , so this system was easy to introduce. I simplly placed her piddle mat in the sturdy sided piddle box and she used it immediately. With a straight lower pad holder, she was peeing at the side and I was constantly having to clean the surrounding floor . Now, it is all contained and she is happy with her new 'piddle place'. And, I am very happy too !!

Perfect for dachshund
This is the absolute perfect size and with sides. I have one without sides and it's great but my dog has decided to stand on the edge and sometimes pee goes off or poop. Also he will be excited when I get home and try to pee fast and run and it gets on the floor. This will slow him down a little. The grid is almost too small and it holds pee. I have to wipe it everytime with a paper towel. I have a 10lb dachshund. He is long and he has plenty of room. I have 23x23 pads. I fold one side of the extra plastic down on the pad and it fits perfectly. I highly recommend this one!!!
