ultrahold has been really good for me. i really like the strong bond it creates! i really have nothing to complain. lasts a solid 3 to 4 weeks in a country with a minimum of 28 deg temperature (even as we speak). i have just bought ghost bond now, just cause i'm tired of hearing the good reviews. will report the pros and cons when ive tried it out myself. only small con about ultrahold so far is the cleaning part. its messy sometimes, takes a long time to clean and youre almost sure you'll never get a perfectly clean lace after using it, no matter how hard you try to clean it. and take it from a persistent me... sometimes spent over 45 mins just trying to get rid of the messy ultrahold.
