I recommend that before using an AUR helper, you should familiarize yourself with the process by cloning, reading the files, compiling, and installing manually. Then after you think you are good you can install a helper. I use yay.

Also, sometimes pacman itself gets updated and your AUR helper doesn’t work anymore. When that happens you have to update or recompile your helper manually. If you are not familiar with the process it can be difficult. I’m talking from experience, one day after an update my helper didn’t work and I didn’t remember how to do all the process manually, and I had to re read the wiki again.
