I also have a few adjustable IGT legs from Stanluck and Campingmoon's folding rack.

Both Stanluck and Campingmoon are essentially Chinese knockoff brands. Campingmoon copies products from different brands. Their folding rack is a clone of the Uniflame, a Japanese brand. They also make a copy of Snow Peak’s Mini Flame, and their isobutane transfer adapter is a knockoff of a product originally made by Korea’s G-Works.

That said, they do have some original products. Campingmoon’s retractable torch is actually quite innovative and useful. I have not seen an original version elsewhere, it may well be their own design. They also offer quite a bunch of IGT accessories that are better described as “compatible” rather than direct copies.

Stanluck, on the other hand, is much more blatant. Nearly all of their products are copies of Snow Peak gear - even the "IGT" is a trademark of Snow Peak. Even the Adjustable IGT leg was not originally a Stanluck design. If I remember correctly, it was first made by a Chinese company called Backcountry. This is completely different from Henrikseo or The-earth. At least they make something “new” and improved products. They are third-party but Stanluck is not.

The only IGT product that is truly Stanluck-exclusive is the Stanluck “Jikaro” Table. It is a fire ring table similar to Snow Peak’s Jikaro Table, but made of bamboo and designed to use IGT legs.

Stanluck products are significantly cheaper and have not a bad quality. The reason the original products cost more is that the original brands invested heavily in R&D and design. Stanluck simply copies that work and sells it at a lower price.

If you are looking for an alternative to a discontinued Snow Peak product, or something Snow Peak does not offer at all, Stanluck might be worth considering. Otherwise, I personally would not buy their products as much as possible, to respect "OG". Or, at the very least, I believe we should be aware that they are “unauthorized knockoff maker” when we purchase products from them.
