Fishbones Gravity Hook a number of times, and have been involved with beta testing, so my appreciation and bias is pretty well known.
It appears that the Kickstarted design that Eldrick Garcia and his team developed, over many iterations, and put into production has been copied and is now for sale and being plugged online. Now, I am all for free market, and it's inevitable that great ideas will be copied, I wanted to try at least to compare and contrast the two designs.
Here are the two hooks side by side, with the Fishbones version on the left, and the Molibao version on the right. You can see they are essentially identical, remarkably so. The "arms" of the hooks are essentially carbon-copy of each other. The arcs, bolt-holes, the middle-notch hole and even the curves of the hooks are identical.
The mounting hardware is different, but bolts and self-locking nuts are ubiquitous, as are the shackle loop at the bottom. No big issues with that, obviously.
The batarang cross-hook pieces indicate pretty well the differences between the two pieces however.
The Fishbone cross-hook is obviously thicker, which is true for the entire construction which is made out of 1/8" thick 304 stainless steel and all of the Gravity Hooks and weighs 360g all told.
You can also see the finish of the Fishbone hook is much neater, with the Molibao finish having a notch still present inside the cross-hook. Thicker steel means stronger steel in my books, assuming it was the same grade, which I have no way of knowing.
The differences between the thicknesses of the steel used between the two Gravity Hooks have been taken into account in the Molibao version, which was good to see.
The notch-holes were differently spaced, and adjusted to still ensure a good fit, so the hook actually works identically to the original.
Essentially, if you didn't know that it wasn't from the original manufactures and had one to had to compare with, you wouldn't know it wasn't an original.
One thing I wanted to cover, then, was the price point. I went back and checked the Fishbone website and the steel Gravity Hook is $39.99, the titanium version is $79.99
On the Nifty Thrifty Store site, where I -think- you can get the real deal (maybe, given the use of the official promo-shots) they are $65.37.
The Molibao versions are on AliExpress and other cheep-gear sites, but really, you get what you pay for. I know you're not supposed to be putting your life on the line (literally) with the Gravity Hooks, but, why not spend a little more, for a better quality, original product, and give back to the people who are doing the innovation in the first place.
