pre sterilized spawn bags?

I want to try this method I plan on using the same bag start to finish. Basically I was wondering first has any one had success with these bags and where would the best place to order these. I don't have access to a pressure cooker so this sounds a little more convient for my situation. And if anyone has some insight on maybe some steps to follow. This will be my first attempt so any help will be appreciated.
And I know I should buy supplies and do a pf tek. But currently not an option for me.

Actually. I prefer this over a kit. It would save you $. And get you at least a little better feel to of things. I've read threads with guys using them on this site and others over the years. Basically you get a syringe. Inject a coupla ccs into the self healing port. Store it in a nice temperate area 78f - <90f. Decide upon fruiting or bulk while you wait for full colonization. If it is alot less.than a kit. Buy two.

That's what I've been thinking. Its been rather difficult to find any straightforward information about using the bags. Any recommendations which site to use . I've found many but unsure which ones r fast shipping and sell reliable products. I hear alot about people contaminating their bags

See if the bag has a self healing injection port. And if it is "breathable" or the ability to exchange gases. Almost like a whatman. Like a filtered air hole. You can google the item. Go to other mushroom sites legal or not grows. Even amazon for customer ratings/reviews and see if the prices are better. Then after you order the syringe and bags. You can think upon the next step.
