The kit looks ok, but not thrilled about kits. It's missing some flasks to mix it in, some glass rods to stir it with. When I went DIY I bought,
!) 100 ml flask for small batches
2) 250 ml flask for larger batches
3) 25 ml syringe
4) 10 ml syringe
5) 5 ml syringe
6) 1 ml syringe For test batches
7) 2 glass stirring rods
8) full size selection of blunt nose syringe needles. Actually use these more for wrapping coils than mixing. lol.
Then of course Nic base, recommend getting it in PG instead of VG. PG being thinner and easier to draw and measure.
VG, PG, and a bunch of extracts.
You can add more lab ware as you go along, I bought a 50 ml graduated cylinder, and then a 500 ml beaker for mixing large batches of base.
I bought the Erlenmeyer Flask, because I like the funnel shape and figured they would be great for swirling the juice to help with the mixing. Then I got the large griffin beaker for large base batches.
Everything in the list I find is essential for my mixing needs. My add-ons I could do without but come in handy when I need them. Mixing is very rewarding, and there is comfort in knowing that I have enough nic base, VG and PG to last me for over a year. Have a bunch of extracts too, but will probably have to buy some more before 2015.
So yes, if you are interested in DIY juice, definitely go for it. I figure that my cost for 50 ml of juice is less than $4 to make, including lab ware, and that was with my first purchase. Since then the price has dropped some more, since I bought much larger quantities and had free shipping to boot.
