Metal V2 Electromagnetic Reciprocating Piston Engine Model Motor PhysicsFeatures:
.V2 electromagnetic engine model, mini modeling, designed with CAM, the main body is made of metal material, the overall mechanical sense is full; Fine production, craftsmanship, perfect combination of parts, highlighting the precision of the production technology.
.6-12V voltage supply, 2S-3S lithium battery is recommended. The strong magnetic piston supports positive and negative rotation, and the iron piston supports unidirectional rotation.
.Electromagnetic Engine Working Principle: Electrical energy into magnetic energy, the magnetic energy into mechanical energy to do work, according to the same, opposites attract magnetic principle, scientific use a small amount of electrical energy to generate strong magnetic energy, by each cylinder magnet in mutual exclusion, and set the scope, produced strong repulsive force and suction force, force the magnet, The connecting rod drives the crankshaft to rotate to complete the working process of the engine.
.Wide Application: Through the operation of the model, full of interesting, but also can deepen the understanding of the electromagnetic engine structure and operating principle, improve the interest in learning scientific knowledge, for scientific teaching experiments or teaching, can also be used as a DIY model collection.
.Note: 1) when using the machine model, please do not run for a long time, the power of enameled wire is easy to generate heat, strong magnetic field at high temperature for a long time is easy to weaken the magnetic, machine operation has a certain impact, the temperature is too high, please immediately stop running, to prevent scald (the limit temperature of strong magnet 80℃, enameled wire 200℃). 2) The piston mouth of this machine is an open cylinder hole, inside is a strong magnetic piston, easy to attract iron metal objects to the body, resulting in the piston stuck, unable to run. Also do not add lubricating oil in its internal, resulting in adhesion of more dust. 3) This product is suitable for people over 14 years old to use, play, static display, etc.

From a Long Time Hard Sole Dress Shoe Wearer, These are a Must Have!
Size: 12, Color: Blue
I have been wearing hard sole dress shoes for decades and with the full COVID shift to dressing super casual in a professional work environment, I was in the market for some more casual let dressy shoes that were a heck of a lot more comfortable and flexible than my hard soles so I thought I would give this brand and style a try. Oh man, I'm in love. These give you that dressier look yet you can totally dress them down with jeans or cordouroys, so versatile. As I did with my hard soles, I inserted one of my Nike Air in soles and man, these are so comfortable I bought navy and brown! I usually wear these with thin dress socks and they go perfectly with any type of suit set, a no brainer purchase here. I'm a 12 and bought a 12, perfect fit, not to skinny, not to wide, just right. Bottom sole grip is impressive, never felt unstable, solid rubber sole here. I decided to lace them up so there are not tying and the tongue does slip down sometimes so with this feature, best to use a metal shoe horn, then it's super easy to slide them on, they seem to take a beating and remain clean too, I've definitely scuffed them up against many things and still no damage, it's crazy, must have a great finish. NOTE TO Note to MANUFACTURER/SELLER - You need to make a version in GRAY in this specific style and I will buy them instantly, and I assure you they will be incredibly popular! Really not sure why there isn't more colors in these like gray, shades of gray, maybe red, lighter blue and maybe some with different tones in standard colors. Casual dress shoe wearers are looking for new and exciting bold colors so this is the perfect shoe type to deliver on that.

Finally, a dress shoe that actually feels like a sneaker!
Size: 8.5, Color: Dark Brown
I was honestly super skeptical about buying shoes on Amazon, especially "dress sneakers." Usually, they either look incredibly cheap in person or they completely destroy your heels within an hour. I am so glad I took a chance on these Bruno Marcs.
I commute to campus and take the bus almost every day, so I end up doing a ton of walking. I needed something that looked sharp and put-together, but I absolutely refused to sacrifice comfort for a long day on my feet. These completely hit the mark. Right out of the box, there was zero break-in period—no stiffness, no pinching, and no blisters.
They are incredibly lightweight, and the material actually looks premium, not like that shiny, fake plastic you sometimes get at this price point. The traction on the bottom is surprisingly good too, which is a lifesaver when I'm rushing to catch my bus on rainy mornings.
If you’re on the fence, just get them. It’s rare to find a shoe that balances looking professional with feeling exactly like your favorite weekend sneaker. Easily one of the best wardrobe purchases I've made in a while!

High quality, perfect color and very nice price!
Size: 14, Color: Brown, Size: 14, Color: Brown
I bought this shoes for my husband's Christmas present, so he didn't try yet. So far, the color is perfect! I feel like he can wear this shoes with different outfits, for the price it seems hight quality, it is not heavy at all.
The shoe features a soft, comfortable lining and the sole is perfect because it is non-slip.

These fit very nicely, are comfortable, and work for my wide feet!
Size: 12 Wide, Color: Brown
Once I learned while shoe shopping in my youth that I needed wide-sized shoes, I wasn't able to easily choose from any shoes I saw in the store. I usually have to go find the wide widths and have to deal with the limited styles they have. Shopping online has been hit and miss, too. Sometimes, shoes are advertised as wide width, but end up still being too narrow.
These shoes fit me just right. They were not too tight at the toes, gave good width at the arch, and the opening was large enough that I didn't have to undo every single lace just to get my foot in. They also look nice, and I'm sure will take a decent polish.
Also, note that this does say it's an Oxford shoe, but it does have the open lacing and is more of a derby-style shoe. This also helps with sizing for my wide feet. If I didn't already have a pair of black shoes, I'd look at picking one of these up.
My only reservation with these is that the soles are not dark-colored to complement a more formal style. I feel the white makes them a little more casual. The sole is also more transparent/opaque coloring at the heel and underneath, which you can kind of see-through, so keep that in mind. It's not fully clear, but is kind of transparent, which I was not expecting. I think it also shows where it picks up dirt as you wear it. Just more of a style cue one way or another.
As a reference, I buy the 4E wide and Extra Wides in New Balance and Skechers. I also have a hard time getting any good fit in Nike shoes.
