We've been running these through the shop for about six weeks now, and they're holding up better than I expected for the price point — the 400W motor is actually pretty consistent at 0-3000rpm under load, which matters more for clean cuts than the raw number suggests.
The 55mm wood depth is fine for most trim and panel work we do, though if you're regularly 2x4s or thicker hardwood you'll want something with more torque, this is really a finish tool not a demolition saw.
CE and GS certifications were a must for our compliance paperwork, and the FFU Good rating is basically their internal quailty tier, we usually have stock but confirm lead time if you need more than 50 units or so.
it come in a color box with one blade and a hex spanner, which is about what you'd expect for this class of tool, the blade is usable out of the box but most buyers swap it for a finer tooth version for cleaner curves.
One thing I noticed during setup is the variable speed trigger has a nice progressive feel, not just on/off like some cheaper units, and the cord is long enough to reach across a standdard workbench without an extension.
We ordered 200 pieces initially and the packging was solid, no damage in transit, and the 1-year motor failure which is main thing that goes on these, the inner hex spanner is for blade changes and it's easy to lose so order spares.
