Is your big block running hot? Flowkooler designed a high flow water pump with a CNC machined billet impeller with 16 vanes, integrated shrouding and a reduced casting-to-impeller vane clearance. It achieves greater flow rates, higher head pressure and a more efficient flow. The impeller color is due to Type II Class II military grade surface coating which protects against corrosive fluids.
FlowKooler introduced the first hi flow pumps and continues to improve impeller design. Why is increased flow so important to cooling a hot BBC engine? Because it has been proven time and time again that reducing the cycle time between the heat source and the heat sink creates more opportunities to shed heat and drop engine temperatures.

Not as Smart or Interactive as You Think it Will Be
Color: Blue
This is an honest review from a schnauzer owner who has has wanted this cheerble ball for their dog for more than one year. I finally bougI finally bought this toy and both me and my dog are disappointed. The settings are...i would say dog friendly as I'd assumed a dog ball would be. What I mean by that is, for example: the calm play setting is muuch too calm. Super light puffs of energy, like a battery is dying. And the playful setting is scary, alarmingly so. The intervals in between are too long. The ball does not bounce. So they just have settings all wrong. The size is good for a large dog only. Do not buy if you have a small to medium dog. I even think the material is okay. I've only had it for a few days so I can't even speak to how the material holds up. Really hoping to love this ball for my dog. It was not the distraction I was hoping it would be so I could work from home while my dog had fun. I'm hoping this can help someone else who's been pining over it. Essentially, it's a $35-$50 well made weighted ball that moves occasionally.

Brilliant fun for dog, except for...
I have a 3yo German Shepherd Dog (GSD) and he can be very hard on toys. On days 1 and 2 he had such fun and we laughed at his good times!
Then...Day 3...cue the Jaws Music... While I was away for 10 minutes, he dismantled the ball into tiny pieces! Even so, the ball continued to light up, make sounds and entertain my GSD!!
Coolest dog toy ever!
If you have a heavy chewer....watch out!
Otherwise, I highly recommend!!

Disappointing Dog Toy – Short-Lived and Ineffective
I purchased this dog toy hoping it would keep my dog entertained and engaged, but unfortunately, it has been a huge disappointment. The first one I received only worked for about an hour before completely stopping. I decided to give it another chance and ordered a second one, hoping it was just a fluke. Unfortunately, the second one lasted even shorter—only 30 minutes—before completely ceasing to function.
It no longer vibrates, rotates, or interacts in any way. Even when fully charged, the toy barely lights up and doesn’t do anything useful. This is a terrible product, and I’m genuinely shocked by the positive reviews. Save your money—this toy is not worth it.

My dog loves it
My Aussie loves it and he is a tough chewer as well, so it goes great with his hyper reactive personality. Durability could have been a little better, sometimes I have to take it apart and make sure it’s still in a good position because my dog will pick it up and drop it. With no cushion it did start malfunctioning at about 2 weeks. However, it does still work fine and he loves it even without the movement.
Note if you put it in a sock to protect it, my dog goes dangerous and held the sock and created a slingshot lol.

My Rottweiler loves it!
My Rottie plays with this for hours at a time! He loves it! It fun to watch too! The plastic is high quality and has lasted for 2 weeks, so far. That pretty good for a Rottie toy! He loves the lights,
vibration, and the fact that it rolls away. So fun!
