I have one of these https://www.amazon.co.uk/Blackroll-mini-fascia-roller-self-massage/dp/B085DQBW11 that I used on my forearms when I was climbing a lot more than I am now and it's great (recommended by Cristiano Costa when I went to him with a finger injury). I have considered an armaid multiple times in the past but couldn't really justify the price to myself.
