Stark Brushless 220V AC Asynchronous Motor Model Motor High-tech ToyFeatures:
.Original Design Intention: An asynchronous motor is a motor that uses alternating current to rotate, without carbon brushes, no magnets, and generates an alternating magnetic field by alternating current. The alternating magnetic field causes the rotor to induce current, and the induced current generates an induced magnetic field. The internal and external magnetic fields interact to drive the rotor, and spin constantly.
.This product uses a fully transparent structure and uses a ring-shaped silicon steel sheet as the core. It has a novel shape and a sense of technology.
.Technical Points: Customized ultra-thin silicon steel sheet, 24V 24W transformer, hand-wound high-precision coil, transparent structure, dynamic balance rotor
.It is easy to use, simple to operate, safe and risk-free
.It can be used when it is directly connected to a 220V socket
.It is small in size, sturdy in structure, and convenient to carry
.The switch can be switched forward and reverse.
.How to Use: First insert the plug into the base of the product, and tighten the nut on the outer ring to prevent it from loosening; turn the switch upwards clockwise, and turn the switch downwards counterclockwise.
.Notes: The product cannot change the power supply voltage and power privately; it is strictly forbidden to connect wires without permission; the coil may become hot after long-term use, and it is recommended to cut off the power for two minutes after 10 minutes; the product is heavier, please handle with care to prevent damage to acrylic Board; 110V power supply is also possible, but it may rotate slowly.
.Significance and Value: This product can be used for teaching demonstrations to explain the knowledge of AC asynchronous motors. It can also be used as a desktop technology ornament. It is more exhibitable. It is also suitable as a popular science educational toy gift for students and children. It is magical and fun, and stimulates learning. Enthusiasm and interest in scientific exploration cultivate innovation and creativity.

Great little temper
Size: 53mm, Color: Silver
Works great! Only problem is that it doesn’t have that feel of tamping. Wish I had more feedback. It just goes down very easily and doesn’t have that feeling of solid tamping. Now that doesn’t mean it’s not doing its job. Works fine but would like some manual feedback.

Take the guess work out of the flow!
Size: 58.3mm, Color: Black
I got this because when my wife makes espresso, it's watery. When i make it, it's fine. We needed a controlled Tampering method so we both do the same job.
This is heavy, and being able to use the whole hand instead of fingers, not much effort is needed.
Since we purchased this, we were able to make consistent espresso shots for sure.

Not as good as I expected
When it first came, the box fell apart as I was taking it out, and a lot of some kind of dirt or sand kept falling out all over my table and floor. I had the take the entire thing apart and thoroughly wash it.
After drying age reassembling it, I tried it on my portafilter that came with my Breville Barista Express, but, somehow, it doesn't always make the tamping level. You would think with the ridge that rests on the side of the portafilter that it would force it to remain level, but, somehow, it doesn't, at least not consistently. It also has varying lengths (heights, or depths), and a single spring tension, so you may still over tamping or under-tamp. I was expecting it would have a censor that would just detect once it reached 30 lbs of force and cut off after that, similar to a torque screwdriver, but that's not what this is.
I'll still give it 3 stars because, despite the problems mentioned above, it at least produces some amount of consistency, even if that isn't measurable; but, I can't give it 5 stars because of those issues mentioned above.
