I agree with Vacutech.
Theyre Cylinders last a LONG time, and dont scratch or break easily.
Their Hand Pumps Suck though. Theyre cheap.
I recommend getting a Mity-Vac with a gage, OR if you look at LA Pump Works homepage, they have a metal hand pump with a gage. (This is what I have).
Watch for connectors, Most are CTC quick disconnects.
Ive tried LA Pump Works tubes, and theyre thin and cheaply made.
Can't comment much more on Joe Kaplans stuff other than you have to enter a credit card before you can find anything out (Rip off artist).
Make sure you measure properly, and order a tube accordingly. Ive found Vacutech tube chart to run a size large, but you may want to get a couple tubes anyway so that you can move up.
On the black and blue...
NEVER go over 5mmHG of vacuum. Especially if you are a new pumper.
You CAN do damage to your blood vessels if you apply too much vacuum.
I can't stress this enough.
SLOW and Lower Vacuum produces BETTER results.
Start out with 15 minute sessions, and take 5 minute breaks.
Massage your dick down to a flaccid state. Wait 5 mins, then restart...cycle.
Eventually get up to 45 min to 1 hour cycles. I take Frequent breaks, so that fresh blood, oxygen and nutrients can replenish the cells, not suffocate them.
Gains dont happen overnight. Id recommend ever other night, with a combo of Jelquing. Stay with it. Its like exercising, and you are out for Tissue Growth not damage.
Just like lifting too much weight can damage muscle tissue, you can TEAR and damage Valves in your cock where you'll have a limp noodle for life.
