I wasn't sure about using SSS in the end as they didn't seem to stay far enough away from me, so I bought Lifesystems Expedition 50 Insect Repellent as a back-up and I'm glad I did, it works great for me... I'm sooo happy
I recently stayed on Alvie Estate, up near Aviemore, for a long weekend and the midges were out in force, but where I had sprayed myself, they didn't even land on me
Normally I would've been bitten to smithereens.
