.This Stirling engine model adopts T-shaped rocker crank α structure, which has the characteristics of high power and high speed; the moving parts of the whole machine are inlaid with rolling bearings, and the friction coefficient is low; the cylinder piston is precision ground with SUJ-2 alloy steel, with clearance Precision, high hardness and good wear resistance; the overall connection is fixed by screws, all connection parts are sealed by copper pads, and the performance is reliable and high temperature resistance; high-density aluminum alloy heat sink, higher heat exchange rate; base with double-layer spring shock absorption, Smoother operation; all-metal material, ultra-small size, compact structure, high reliability
.Industrial-grade processing level, creating an all-metal exquisite model, unique and innovative, is a novel fashion gift and collectible; the whole machine is assembled by more than 150 small parts, including 12 rolling bearings, 30 stainless steel bolts, etc .; the appearance parts are made of 6061 Sandblasted and oxidized surface of CNC aluminum alloy after processing
.Instructions for Use and Maintenance: (1) Before use, dial the flywheel to check whether it rotates smoothly, if there is excessive resistance, check if the cylinder is blocked by sludge, and if necessary, remove the cylinder assembly and wipe the piston and cylinder with alcohol. And apply graphite lubricant on the surface of the piston; (2) Inject 95% alcohol into the alcohol lamp (capacity is less than two-thirds), then ignite the alcohol lamp and place it under the heating cylinder to heat for 40 seconds (the flame should be in the heating zone as much as possible) , At last you can rotate the flywheel at high speed
.Note: (1) The heating source will cause the body to generate high temperature during operation. Do not touch the high temperature parts such as the heating cylinder and heat sink, otherwise it will cause thermal burns; (2) Use only ordinary alcohol lamp heat sources, and do not use windproof lighters. And other high-temperature dark fire heaters (above 500 ° C), otherwise it will cause damage to the piston cylinder at high temperature and high speed operation; (3) Do not apply any lubricating liquid grease to the piston cylinder, otherwise it will cause excessive resistance and fail to work; (4) The machine has a starting compression force. It is recommended that novices use the engine base to start for the first time use, which is easier to control.

Thick indoor balls, of a darker pink color.
Style: 6 - Pack, Color: Pink
Good indoor pickleballs. The description said they were outdoor (thin crisp plastic) but they are thicker. By the picture on my pc monitor, they looked brighter pink than they actually are. I was hoping to use these outdoors in the early morning rising sun, on a blue court with yellow green edging, but the color is too dark to be of use. So when we move indoors for winter, we will use these indoor balls there. They arrived quickly and were well packaged.

Great but hard to see when playing!
Style: 6 - Pack, Color: Purple
The balls are great but when playing with them, if you wear glasses the ball is a little hard to see. We played with the orange, yellow and green balls, which are easier on the eyes. Otherwise, the balls are great! 😍

Great value
Style: 6 - Pack, Color: Purple
Although pickle ball snobs have told me these are NOT proper outdoor balls, I love them! Not only are they a fantastic color but I like the weight of them and they are great for outdoor play. As a bonus, they are well-priced, so I feel I got bang for my buck.

Bright color easy to see but not a great bounce on the outdoor court
Style: 6 - Pack, Color: Pink
I liked the fact that these balls were a bright color and easy to see but the bounce on them was not as good as other name brands. They were OK as a back-up and performed better outside then on the indoor courts which are made of a different surface. We are using them , but would most likely not repurchase.

Price was best I found for quantity anywhere
Style: 6 - Pack, Color: Purple
I am a beginner and by no means an expert, but these balls appear to be as any other. The couple at the next court had a Franklin ball that came our way, and I bounced it and popped it back - I couldn't tell any difference in that instance. Sports stores had just one color - yellow (maybe one had chartreuse) amazon has single colors multiple - I thought it was worth this purchase. The purple may be harder to see on cloudy days - as I had on sunglasses and I could see it, but the fence at the court has a "privacy" net, it kinda bleneded in for a very brief moment until the sound was heard of the return, then no problem.
