I would like to clarify that I have not used the air compressor much since I bought it. From the very little use I have done, I have found that it is a very high-quality product. With oil and careful construction, it is lightweight for transportation and has tolerable noise. Compared to other models, it makes less noise due to the oil, but it is not completely silent. However, I don't think there is a completely silent air compressor for this price or maybe even more. The upright placement is very useful as it requires less space. When I use it more, I will come back if I find anything else.
