yeh there is a lot of products that are voltaren based wit that active ingredient.
Nurofin has ibuprofen / codine which some use as well, so not only voltaren but a few major ones there that have potential nasty side effects.
I am suprised that a product that has a chance to cause stroke / or liver damage is being sold on self given the tight TGA standards.

The question is how many products are of near quality as thermalife which is in the same or similar price bracket?
dont worry bout the cheapo stuff they sell for 6-10 dollers as people can not simply dismiss a unconfort such as this and will spend extra to get a superior product.
