Ok so I unboxed and took some pictures of the ZB2520HL Reflow Oven, those are available here:

- The box was pretty banged up in one place, the oven itself shows no sign of problem yet though.
- I asked for the 110V version, it came with a beefy molded plug on a H05VV-F 3G 2.5mm cable which seems to be rated for 25AMP.
- The fuse at the back of the unit is a F20AL250V which is a fast blow 20Amp fuse.
- There was a significant ding protruding from the front of the tray, looks like something hit it very hard from inside.
- The unit feels robust, the case doesn't have lateral movement, good rubber footings, the tray slides well and has a magnet to hold it closed.
- I needed to pull a bit on the side fan grill to prevent it from rubbing against the fan, it was making a very loud whirring noise.
- As soon as the back power button is ON, the side fan turns ON and emits roughly 58dB from 1 meter away.
- Pressing the power button under the display illuminates it and gives access to the pictured menu in english.
- The material inside the tray and the oven looks like those insulated aluminum wafers found in toasters.
Thats it for now, tomorrow I will take some time and pop the top off to see what the inside looks like
Edit:
Ok I lied, I couldn't wait until tomorrow... I added 4 pictures showing the inside when you pop the top off, so far no sign of the awful masking tape and no obvious wiring problem (ground looks decent). I don't have a board ready for soldering yet but I will lay a couple of scrap pcb pieces, start the reflow, at the peak of the reflow profile I will open the tray and check what the temp looks like with a thermal camera.
