I’ve seen it listed a bunch but i want to highlight project farm.

It is a great channel that tests everything tool related including commom household products. Definitely check it out before buuing any tools really.

I’ve used aliexpress for bootleg lego and have had mixed results. Some sets were perfect copies with all pieces, and others were missing some. I was also able to get some discontinued sets which was nice. The quality of the pieces themselves were pretty good. It is a bit of a risk but hard to beat the price as its wayyyy cheaper.
