Product Name: Stirling Engine Model
Color: As shown on the picture.
Material: Metal,Glass
Usage:
1. Security start step
(1) Put the engine model in a horizontal position.
(2) Turn the flywheel gently with the hand, check whether the flywheel is running smoothly if there is a strong sense of astringency, check whether the connecting rod is connected to normal, whether the piston in the air cylinder and the spindle on the copper sleeve have oil if there is a dry cloth or toilet paper with oil. Wipe the piston and the outer wall of the spindle, confirm that there is no oil stain or foreign matter to ensure that the flywheel runs smoothly.
(3) Check whether the two crankshaft angle on the flywheel is 90 degrees (the crankshaft is at the bottom or the most right side of the crankshaft at the bottom), if it is not to be adjusted in parentheses.
(4) The alcohol lamp is moved to the hole of alcohol lampholder, and the alcohol lamp is ignited on the premise of confirming safety.
(5) After heating for 60 seconds, start with your hand gently toggle the flywheel until the flywheel can run automatically.
(6) The whole process of heating must not touch the main cylinder (high temperature danger!).
2. Security end step
(1) Please let the engine model cool down after use.
(2) If the end of the way is to end, the alcohol lamp is extinguished to confirm that it is completely extinguished, please let the engine model naturally cooling in the cooling process to stop operation automatically.
(3) If the engine model is cooled down naturally, please keep the engine where the child can't get it.
(4) Children should use the engine model under the care of adults, so as to prevent scalding or accidentally breaking the glass.
3.Matters of attention
(1) When alcohol is added to the alcohol lamp, please confirm that the alcohol lamp is in the state of extinction.
(2) If alcohol is inadvertently sprinkled on the model floor or on the desktop, please wait for the alcohol to evaporate completely or dry the alcohol, and then ignition.
(3) The wick of the alcohol lamp can not meet the test tube, and the light core will produce water vapor when it burns. If it meets the test tube, it will break the test tube.
(4) The engine model has high rotational speed and will vibrate when running, so be careful to slide down from the table.
(5) Be careful when heating, prevent scalding.

Best leash we’ve owned in 36 years of dog parenting
Color: Green, Size: Large
Wow! My wife and I have been dog parents for 36 years (six dogs), and this is the best leash we’ve used.
* Two handles: I used to think the second handle was unnecessary—now I can’t go back.
* Comfort: Both handles are padded, so no hand strain on long walks or sudden pulls.
* Tangle-resistant: The swivel between the leash and the loop that goes over the dog’s nose/neck keeps things from twisting, which makes control easier.
* Secure fit: The sizing ring stays put, so it won’t pinch the dog’s nose.
Note: There’s no backup clip to attach to a collar, so a determined dog could slip it if the loop is too loose. Adjusting the ring snugly has worked well for us.
Given the quality and price, I can’t recommend this leash more highly. ★★★★★

Slip lead that doesn't tangled and allows for a greater control
Color: Blue, Size: Large
I'm using this slip lead to volunteer at a dhelter - and what a difference it made! I really like this slip lead leash! Very easy to put it on a pup one-handed, the swivel and second handle make a huge difference! (The main shortcoming of a simpler version of a similar slip lead without a swivel is that it's getting tangled and/or twisted around). This is also high quality item - every detail is thlught through! Very comfortable to use, multiple color options - really nothing negative to complain about! Love this leash!

Second handle too high up on leash
Color: Black, Size: Large
Slip lead length provides your reactive dog with too much range to lunge. The second handle is great but it is too high up on the leash. If the slip lead length was shorter and the second handle was lower, this product would be awesome.

Great lead alternative!
Color: Blue, Size: Large
This works great for an alternative to just a slip lead. I work in a kennel and it makes it a lot easier to grip for the dogs that pull a lot.
