I bought this product in August 2019. It worked fine for 2 months. After the winter break, it hasn't been able to inflate the SUP, it doesn't even provide pressure. From what I saw on the packaging box, it doesn't come with a warranty, so the money went to waste...

Good, it takes 13 minutes for my sup to reach 15 psi. It stops on its own, does what it says. I give it 4 stars because I would like it to have a battery so that I don't have to sit in the car in the sun for a quarter of an hour to inflate it

Very good! I have used it twice without any problems at all. Although it seemed to struggle after 10psi, it did not heat up at all and continued to inflate normally.
