I find the ULTRATHON works well for me too and each application is long lasting (up to 12 hours according to the packet, though I think that might be stretching it a bit). Price wise it is cheaper than a lot of others and a real bonus (for me at least) is Homebase seem to class it as seasonal and sell it off at a silly cheap price at the end of the season. On the downside, it does contain Deet, which some people don’t like and it also advises that it not be applied to cut or grazed skin, which is not always easy when playing with sharp and pointy things….my number one GO TO repellent is homemade, Lemon Balm, Lemon Geranium and Apple Mint Balm/Cream…..keeps the beasties off and is actually GOOD on cut skin, grazes, burns and bites…..In truth though I have never tried either in areas where Midges are really prolific, just around my own ponds and woods. The smudge pots do work (I burn Cramp Balls literally by the bucket full), but unfortunately you nearly have to deliberately sit in the smoke which isn’t a lot of fun.
