Review time!
Overall, I love it. It is an MT3 bottom coil.
Pro's
Being basically an MT3 it gives us in gogo nation an incredible variety of color, size, and finish choices.(cig easy if your reading this too, start stocking more options at comparable prices and I won't go anywhere else for my gogo gear). Any MT3/T3/miniT3 tanks will screw right on to the gogo M1 base! Also, like I said in the other post, you can use any T3S replacement head. Which gives us 3 different choices for resistance! Very little juice will be found on your battery. You can very easily rebuild these heads, just search for pro tank or evod rebuild. Also you can rewick these cotton for better flavor and wicking.
To re wick with cotton:I do this with the coil head screwed into the base, and the base on the device so it's easier to hold onto.Ffirst remove the little rubber thing from the top of the head. Then using needle nose pliers pull the grooved top part off exposing the wick and coil below. Using tweezers or something similar(fine tip needle nose pliers may do it, I use a hemostat from an old suture kit) to remove all the silica pieces of wick. Set them aside. Then pull on a cotton ball or qtip to make a long skinny thread of cotton that is narrow on the ends and slightly smaller than the diameter of the coil. Pull the cotton wick through, cut off the ends to the same length the silica wick used to stick out. Lay a few strands of silica back on top of the cotton wick(helps prevent popping hot juice from jumping up the mouth piece into your mouth). Then replace the top piece of the replacement head, slide the rubber thing back down and voila! Cotton wick, better flavor and wicking.
Con's
Being basically an MT3 it has all the same downsides. Cooler vape(only an issue if you like warmer vapor, I love the bcc vape). While it won't leak much onto your battery(unless you've lost an oring somewhere), it will gurgle occasionally. Especially when you're getting low on juice. To fix this grab a paper towel or napkin and twist a corner long and skinny enough to fit down the air tube and push it down there to absorb the liquid that has collected there causing the gurgle. Orings are easily misplaced while cleaning and filling. Especially one of them. Take note of how many there are and where they are when you first get your M1. If one is missing, you will have flooding/leaking issues. The biggest culprit is the little flat ....... right below where the replacement head screws on. That one likes to come off with your tank or not lie flat. Which it needs too to perform well and not leak.
Enjoy!
