About the WP173 Servo


High Performance

The WP173 servo offers exceptional performance with high torque and high-speed operation. At 6 volts, it delivers an operating speed of 0.09 seconds per 60°, while at 8.4 volts, the speed increases to an impressive 0.07 seconds per 60°. This rapid response time ensures precise control, making it ideal for competitive racing or complex maneuvers.

My dog's favorite
I have a 4 year old german shephard and this is her favorite ball. She often loses them and has to resort to a previous ball she used to play with, but when I line up several balls she chooses this one every time. When I tell her to search for her ball so we can go play she passes by all the other balls we have for her to look for this type. It has gotten so bad that I buy these in multiples because we play so much outside that she looses them and I almost have to order her to pick up an old ball when she can't find this one just so we can go outside. She loves to chew on this ball, I know that she could destroy it if she wanted to but she just likes to half bite on it. My dog loves this because the holes on each end make a whistle sound when you through it and she has become great at tracking it through the air via the whistle, I like it because it glows in the dark. So, in the early morning when she goes outside to the bathroom I charge the ball with a flashlight and I can watch her walk around the yard (we live out in the country and it is mostly dark all around us). Best ball for me and my dog.

Heavy chewer approved.
Style: Ball, Size: Medium (Pack of 1)
My pomsky will destroy a toy in minutes. Ropes, and the "indestructible" nylon type stuffs are no match for my furry shark. This ball has stood up to him like David. He loves the crunch and it is so much more tolerable than a squeaker. These will be a staple in his toy box - Chuckit toys are really the most durable dog toys I have found in three years.

Dogs love them
Style: Ball, Size: Medium (Pack of 2)
Our dogs love these. What’s great is that you can add more plastic (like from water bottles) if the plastic starts to fall out from the center. If you have a chewer, though, these won’t last you long. Our shepherd mix loves these and then starts to pull the rubber apart the more she plays with it. Our other dogs treat it normally, though, and those ones last forever. They also get some decent height when bounced, and they make a unique whistling noise when thrown.
