While not the best, it does a decent job and is easy to figure out what's wrong.

The pump is of poor quality.

The only parts missing are the small, removable plastic ones, which I don't need but would still be useful to have. I need to examine it closely because there's a small tube included, which I assume is glue, and I'm unsure why it's there, since the patches shouldn't need it if they are good quality.

The item arrived well-packaged, ensuring it wasn't damaged. I endorse the seller.
