Definitely happy with these muffins. They are my first few runs. I expect improvement with more runs.

I was just about to order the 15500 Robinair but a few negative reviews on amazon stopped me (like oil smoke and only reaching 25hg). My current gast pump quit pulling 29hg and I'm looking for a reliable 2-stage and not break the bank, I'm only using a vac it pro, do you think I'll be fine with the 15500?

just something fairly cheap, should only have to spend 100$ or so... those 500$ pumps are way overkill and just wasting money for making BHO.
what is your elevation?? have you tried changing your pumps oil? are you sure there isnt an air leak anywhere? sometimes even just a 98% vacuum is the best. at a 99.5% vacuum, THC will boil away at something crazy low like 10 or 15F.
I have had awesome results with a cheap chinese no name one from harbor freight.

I'm around 2000 ft elevation. These pumps I have I am not sure that you can oil them, they're not typical vacuum pumps, I don't know what the hell they were used for but they were in my boat storage space being thrown away. I really try to avoid harbor freight, Mainly I hate going to that side of town, it's a full day trip. I was looking at the 15300 Robinair for 150$ @ amazon

i think mine was 150 or 160 with tax, i agree i think anything over 250 is over kill

also, if youre at 2000 feet, same as me, max vacuum you can pull is 28.7 or so. so your gauge will never go past 28.5 ish... but thats a full vacuum... so once your gauge is at 28" that would be roughly enough and I wouldnt panic if youre only seeing 28"
25" is a hair low though.

I just ordered it, 113$ after my amazon points and shipping, I'm stoked to say the least! Yeah I don't think I could justify paying twice that either, it's nice and all but 200-250$ is a decent amount of product that I can use! Good to know that the gauge won't go to 29 because of altitude, I would have been scratching my head on that one for awhile

yeah ordering online is the best thing ive ever done... and worst thing on my bank account. need something? anything, some random crazy weird piece.. find it in 2 minutes, pay tonight and have it shipped in the morning, providing shipping isnt a deal breaker, and you can afford to wait a week or so. I love it!!!! especially being in canada... your guys' prices in the states are fucking lowww!!! like 40% off everything, or more.

I'm about to buy equipment, probably going to get the robinair 15300 I guess... what is a good vacuum chamber, and do I need anything else for it like gauges or hoses or anything?
