My first purchase with Simrell Collection for my Dynavap army of devices. The steel FMJ - super fresh looking, easy to install onto a captive cap, but most importantly, drives the Dynavap into high performance mode for satisfying one hit extractions. I used to be a low temp person, but don’t sleep on the enjoyment factor of the flavor spectrum hitting you all at once. Working with an IH is a plus, though I feel the torch is the OG design intent of the vapcap. Highly enjoyable and 10/10 would recommend.

Was having decent luck with the standard Dynavap M that I have. There was a little bit of a learning curve as with anything. Thought about getting the Dynavap Armored Cap. $40 is a lot for that little piece of stainless steel. Then I saw a review of the Simrell FMJ add on sleeve for the Dynavap cap. The price was a lot cheaper than the Dynavap model so I thought spend a few bucks and try out the FMJ. I sure am glad I did! This little $10 cap add on has taken my Dynavap to a whole new level. NO MORE TWISTING. Just hold the flame steady on the "S" logo until you get your clicks and BOOM! The biggest vape rips out of the Dynavap I have ever gotten. PLus it stays hot enough to go back for a second or third puff as you clear the whole boal in one heat up. Takes longer of course but only about 10-15 seconds. But so worth it. I love the stainless steel FMJ.

Stainless steel capped worked as described always have great products great service and fast shipping again thank you for your contributions to the vaping community

Makes heating by torch a breeze, I recommend this upgrade for every Dynavap owner

I own the majority of products from Simrell. I have all of the different varieties of FMJ.

All varieties are fantastic to have on hand. Some stay prettier than others but they all serve the purpose of allowing you to not have to rotate if you're using a lighter and if you use an induction heater it's quite convenient.
