.Product Parameters: Input voltage is 24V. The output voltage can reach 100,000. The arc length is 9cm
.High Quality: Capacitor with a withstand voltage of 30kv2000pf, Capacitance with high voltage, large capacity, is not easy to breakdown, the generation of arc is also very strong.

.How to use: The power supply voltage of 24V should be provided by yourself. Open the switch after connecting the power supply
.Precautions: When the marx generator discharges, it will generate relatively large electromagnetic interference. If it is powered by the switching power supply, it is more susceptible to interference and damage. It is best to use a lithium battery pack, a battery, a transformer, etc., which are not afraid of electromagnetic interference. During operation, the equipment should be kept at least 3 meters away from other household appliances to avoid electromagnetic interference from arc

It's what'd you would expect
Size: 58.5mm Flat Base
I work in espresso professionally and got this as a tester for ergonomic purposes.
It does its job as a tamper and does level with little dusting from it being 58.5mm. The self leveling does work. However depending on my baskets (using vst now) it will.self level where the lowest part of the puck is handle side and highest.part opposite. Not an issue with the tamp but something to be mindful of. Works perfectly well on my gaggia setup...not so much commercial grade. The spring is adequate but i tend to tamp a bit harder on heavy weather days..
Build quality is fine but i would have rather used a regular style tamper.
Also palm tampers pretty much need to be self leveling based on the ergonomic nature.

Solidly constructed and has a premium, hefty weight
Size: 58.5mm
Works exactly as described. Can be a bit heavy but otherwise it is a premium built product. If you have too much coffee in your basket and they're near the rim of it, coffee can get stuck to the sides of the distributor. A little annoying but easily remedied by brushing the grounds back into the basket or by "flattening" the coffee grounds in the basket first prior to distributing.

Would purchase again
Size: 58.5mm Flat Base
Fits my Gemilai portafilter perfectly. Works as expected, but can be slightly unlevel in tamping. Has a tendency to push the coffee down more on the handle side of the basket. I try to make sure I apply pressure in the middle of the tamper and it seems to make all the difference.

Size: 58.5mm, Size: 58.5mm
The product is good, I was sent a was clearly looks to be a used product with scuffs on it and some rust, I can clean that up and for what it does, it'll do, just weird to receive a used product.

Great scale that needs some improvements to be perfect
Color: White, Color: White
Very accurate scale, looks good in white, timer works nicely and I do like the concept of the ratio conversion. Shown in photos with 0 measurement drift over time, even without the silicone mat.
To make this the best scale in the price range, I would change:
- The auto timer function. Timing currently stops if you pick up the brew to swirl; you must completely restart the process if you do happen to pick it up. I would change that to only stop on user input (pressing a button).
- The ratio conversion. Why offer XX.0 precision if you can only change the ratio in whole amounts? I'd suggest offering 0.1 increments, selectable with +/- buttons instead of cycling through.
- The silicone mat is not well affixed and slides around. Kind of useless as-is and I just keep it off. I would wrap the whole thing around the measurement platform, similar to how the Greater Goods scale does it, to really keep it secure.
It's not perfect, but for the price, it's a 4.5/5 for me. Rounding up to 5 since a 4 is considered "bad" by today's online rating standards.
