Their 18350’s seem to be one of the best available on the market. They might not be consistent. But they’re probably suitable for most 18350 flashlights that don’t have a >10A current drain.
Reviews by HKJ and Battery Mooch might help in deciding whether to try out a particular cell.
Orbtronic makes no claim of ownership of the cell, they tell you the cell is Panasonic and they provide the protection circuit. How can vapecell take a Samsung battery, put their purple vapcell wrapper on it and call it a vapecell? Sounds illegal no? Can I do the same thing, just rewrap batteries and put my name on it?
I think if you are going to outright copy something there should be disclosure. This is why authors use footnotes, to give credit to the original writer.
Selling products produced by others under a different name is a tried and true practice. For example Kenmore appliances, after-market car batteries (there are only 3 manufacturers in the US), etc.
And with respect to these batteries no doubt the original manufacturers are selling them to Vapcell with the understanding that they are going to be sold under the Vapcell name.
