Features:.The body is made of one-piece aluminum alloy material, which is sturdy and durable. 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 latex pillow
Size: Queen (Mid Loft), Number of Items: 1
This review is for the biamktp queen pillow. Medium firmness. Finally a latex pillow worth keeping. After trying many other latex pillows I'm finally sleeping comfortably. This pillow is soft, yet firm enough to give your head support. I'm not having any neck or shoulder pain when I wake up. I'm sleep on my side about 95% of the time. 5% on my back. I've been sleeping with this pillow for about 10 days and still am happy with it. It was delivered on time, absolutely no odor and it has a removable cover. I highly recommend it.
