Should I Get a Patent?

I’m the only seller of a certain product since it’s my product. I have compared it to the top competition in my niche by buying their products and I have 0 doubt that I have the best product in my niche. The problem is that I don’t have the funds to dump a ton of money into ads (yet) as I’m still getting it off the ground. However, I’m concerned that others in my niche may catch on to my product, come out with a knock off, and because they’ll have more funds for ads, will take me down before my product and brand are known.

That said, should I get my product patented? Will a patent actually protect my product? I see countless of patented products have knocks all over Amazon, so is it even worth it? I already have a trademark, so the name of the product is protected, but I’m wondering if it’s worth getting a patent as well.
