i've never tried the tabs, but i've been using the liquidex and love it, for the price i dont' see any reason to use the tabs, the only difficulty is measuring the liquidex, here is what i did, suck up whatefver, 1 cc or so of liquidex into an 18 gauge pin, THEN grab a 1 cc
insulin pin pull the plunger out, on mine i can do this, BD insulin
pins, then just shoot in your desired amount and shoot it, very accurate, but be careful when i fired tried it i shot like 3/4 a cc into the
insulin pin but when i tried to put the plunger back in i was stuck with an air bubble so my measurements were always off, i should have thought of that first, so just make sure to hold the pin wiht the
needle po inting down and just fill it up until u get your desired amount.
