This really will compete well vs. the Hakko FX-888 IMHO (power rating is much closer). And it should outshine it in regard to it's UI (looked, but didn't find a manual on Weller's site
).
If it matters, the COO = Mexico (ET tips too), but it's no different really than the FX-888 being made in Malaysia as a means of reducing costs to meet it's targets (build cost & MSRP).
For disclosure, I've a WD1 based setup, and it's UI is very easy to use (5 buttons; up, down, and 3 presets). Included set-back features were only timer based, but by adding an optional Stop-n-Go stand (connects to the station, and the handpiece to the stand), it opened up ALL of the setback features. Very nice station, and as the tips are just iron plated on copper, they're not expensive.
