read lot of reviews so took a chance claim 4500 psi needed 4kpsi got 3300psi sent back noise did not bug me high volume fan but the fact that they dont say any where till you get to reading their manual that from 3k to 4k in some tiny container is 25 minutes till you buy it and well it never get above 3300 i can pump with the hand pump i got in ten minutes from 3k to 4 k i would say the reviews that have a low opinion of this pump are the ones to go by look else where i am getting a umarex after refund
