Definitely the strongest s&v flavour I've come across. Munching a whole bag (easy done) and you feel like you need a gallon of water.
Bought these the other day, if you like a strong flavour with lots of seasoning, GET THEM! they are fantastic. Better than all over hand cooked crisps you get which barely got any flavour then after a few bites it's like you just munching potato.
Also love Golden Wonder Salt n Vinegar, but my Icelands doesn't seem to sell them, just the other flavours? will need to look around.
