Angle Grinder - Quadrature VCO / State Variable FilterAngle Grinder is a quadrature sine wave oscillator, filter, and distortion effect. The SPIN section is a quadrature sine wave oscillator. The GRIND section compares each phase against the input signal, then subtracts the resulting square waves from the input signal. If the spin section is either damped enough or enough signal is fed into it from the GRIND section then it will stop oscillating and become a state variable filter. The Angle Grinder

Omg my dog loves this. The rubber is so durable my 2 yo aussie hasnt torn it up yet. I bought a cheap one from temu before and it took only 2 mins for my dog to tear it up it was complete waste of money. I love the football shape becahse it bounces unpredictably. I lile this to exhaust and exercise my aussie. This has become his favorite toy ever. It charges fast too. When im feeling lazy this is good way to exercise my dog and enrich him. I also teach him commands using this ball as his treat or reinforcement. Definitely worth every penny

The best toy for my dogs

I was looking for a toy that could keep my dogs entertained themselves for a long time because with the traditional balls they usually get bored quickly, But I’ve definitely loved this toy , I have two dogs of different sizes and they have a lot of fun playing with it, the ball bounces and makes sounds that really catch their attention, the quality ea great, even though they bite it , it hasn’t been damaged and it is easy to carry it. It's amazing

Didnt last.

Didnt even last a day. My dog is a 40 pound lab mix and figured out how to unscrew the toy within the first couple of hours. He then detroyed the plastic screw system on the inside.

Super fun toy!!

This is such a fun toy! My dog loves running after it. The shape is perfect for a medium sized dog . He isn't into the round balls, but this football shape is easier for him. I love the automatic movement because it don't have to contactly be throwing it.

Great toy

Color: Blue

Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.
