If you read enough documentation and marketing information about VEDs, you will find that safety is a serious concern. The issue/danger is primarily from exceeding (negative) vacuum pressure limits with can damage blood vessels in the penis. (The other primary danger is using them for too long a period of time.)

This document from the U.S. FDA specifies their safety guidelines for VEDs:
https://wayback.archive-it.org/7993/20170403201650/https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/GuidanceDocuments/ucm072098.htm

Open the document in a browser and search for "17". You will find this sentence:

Vacuum Level – Vacuum pumps typically draw a vacuum of less than 17 inches of mercury. If the vacuum range of a new device differs substantially from that specification, manufacturers should conduct studies to establish the acceptability of the vacuum drawn by their device.

I encourage everyone who uses a VED to pay attention to this number (17). It is a rational safety limit.

Unfortunately my electric pump is cheap and doesn't have a gauge. It has 3 levels but the lowest level is pretty intense. I barely last 2 mins and then have to let the air off. I press the relief valve at last 7-8 times in 5 mins. It seems like the pressure keeps increasing.

Since your pump does not have a pressure gauge, you might want to use this rule (a physician recommendation):

Stop increasing vacuum pressure when your penis feels a light stinging sensation.

My personal care physician recommends this dictum: "If it hurts a lot, do it not."

I have been using a penis pump with a vacuum gauge several times a day for over 10 years. Based on my experience, if you were to subject your dick to a vacuume level of 17 in/hg for more than 10 minutes you’d develop significant bruising and possibleI blood blisters on your glans.

The accepted rule of thumb among “professional” pumpers is to limit time under vacuum to less than 20 minutes and a maximum vacuum level of 5 in/hg.

My recommendation for those without a vacuum gauge, is to pump until you feel slight discomfort and then back off slightly.

Hey dt. thanks for the insight. May i ask how has your penile size been throughout this time? maintained? increased?

During my first four years or so, I gained almost 3/4 inch in erect girth. Over the succeeding years I increased my girth up to a little over one inch - 4.4” to 5.5”.

With regard to my original post quoting the FDA on 17 in/hg, I strongly recommend that readers follow your recommendations, not what the FDA says is the maximum safe limit.

For all we know, 17+ in/hg might be the threshold for a penis explosion.
