It has an aluminum alloy base to reduce air leakage, higher precision, smooth use, worry-free and durable, and the texture and appearance are superior. After assembly, the flywheel is not easy to deflect, and the integrated flywheel can not run. Bias phenomenon
.Easy to assemble, even novices know how to assemble, reducing the failure rate and increasing stability
.Instructions for use: The base of the machine is made of aluminum alloy. The base is 10 cm in diameter. The cup (the diameter of the cup is less than or equal to 10 cm, so that Sterling does not fall) is filled with hot water (the water temperature can't be lower than 65 degrees, the machine base) At least 50 degrees to run), the hot water level is close to the mouth of the cup, which will make the Stirling base heat faster. Preheating for about 1 minute, turn the flywheel by hand, the machine can run by itself
.Note: It is forbidden to bake for a short time and it can be operated. Long time, poor temperature control will cause the rubber between the base and the fuselage to leak. It can not be soaked in hot water. It will also cause the rubber to leak out. The heat source cannot be iron cobalt nickel because the magnet in the middle of the sponge piston is magnetic. The material will suck and cause the machine to not turn
.The product is suitable for people over 8 years old. Under 13 years old, it needs to be used under the supervision of adults.

Great fun for dogs!
Color: Orange
Two of our dogs really love this! It caused a lot of barking and chasing and running around trying to grab it. It's really funny to use the remote to control it (and especially make it stop when things get a little too chaotic!) It feels durable even when pawed and bumped into and stepped on. The battery life seems good. I plugged it in overnight to charge so not sure how long it took to charge, but it has lasted quite a while with the dogs playing with it and still doesn't need a charge. It's easy to screw off one side of the ball to plug it in to charge. The size is a little bigger than a tennis ball I would say and has a soft texture.

It doesn't work.
Color: Blue
The two halves of the ball shell come apart again and again when the dog plays with them. When it is time to recharge the core, it will not take a charge. The dog loves it, but it's unsafe to play with.

My dogs fight over it
Color: Orange, Color: Orange
Easy to use, durable, and has a great battery love. At first my dogs were curious and unsure about it, now its become one of their favorite toys. They'll stare at it while its being charged and impatiently wait for it so they can have fun again. Perfect size for most breeds.

Awesome ball and made to last!
Color: Black & Yellow
Awesome ball! My dog loves it and plays with it all the time. He's a very aggressive chewer and there are only a few toys he can have without destroying them. Very pleased with this.
