This is a 20-bar espresso machine sold under the name oveisn, built around a bean grinder with 20 grind settings and a touchscreen control panel. It is also one of the least documented machines we looked at — there is essentially nothing to go on besides the seller’s own description.
What is actually documented
The listing describes a 20-bar pump, a built-in grinder with 20 grind settings, a milk frother and a touchscreen interface, positioned as a “professional home espresso maker.” That is the full extent of the specification available. We found no separate manufacturer site for the oveisn brand, and no spec sheet beyond the marketplace listing itself.
What nobody has verified
Wattage, water tank capacity and physical dimensions are not stated anywhere we could find, and no independent outlet has tested this machine. Built-in grinders are one of the harder features to get right cheaply — grind consistency and dose accuracy are what separate a usable integrated grinder from a decorative one — and nothing here speaks to which this is. The 20-bar pump rating describes the pump, not the pressure coffee is actually extracted at; nine bar is the conventional target regardless of what the pump is rated for.
What to ask before you buy
- Ask the seller for the actual wattage and water tank capacity, since neither appears in the listing.
- Ask specifically how the grinder is calibrated and whether grind size is adjustable in fine steps or coarse presets.
- Ask whether the baskets are pressurized or single-wall.
- Check the return window closely, since no independent source has verified this machine works as described.
