I got my SLX 2.0 a few weeks ago (wasn't sure on it at first, was just a grinder, but now I love it! 4-peice in a 3-peice footprint, and the nonstick is a real nice touch).
No idea what the little pick is for, I haven't used it (I use a lego shovel).
I can't say I can see that your grinder looks off centred going by your pictures. The magnet by be slightly out on the lid, but you can measure to be sure. As for the walls, they do look slightly fatter / thinner, but once again, measure to be sure.
The gasket on mine is flush, apart from where "finger slots" are.
The metal (not sure what one tbh) used isn't smooth, but "lined". You can see this if you shine a light on the grinder.
As for my grinder (to give you something to compare to);
- Mines all fine and centre
- The walls are around 2mm thick all around
- Flush gasket, can't fill it (only on "finger slots")
- The coating is fantastic. Feels wonderful to touch, and the sticky Lemon Haze I've been putting through it is no troubles at all. Same goes for the kief chamber, so easy to work with.
When I compare the SLX 2.0 to my old £10 ebay special; it feels a hell of a lot better made in every regard (the SLX that is).
Defects happen all the time (cars, computer parts, the food you eat...), this just sounds like one of them. Ask you retailer for an exchange (I think the walls is enough to call it defective and warrant and exchange), but do remember, some places wont take back "used" products (yanno, because of the nature of what its really used for
) .
