Got my new DuoMid set up in the garden for the first time yesterday so I could seam seal it.
I noticed that the buckle at the bottom of the zip had a tendency to open slightly – the upper 'tooth' slipped out of the clasp.
I tried slightly bending the tooth upwards, and that temporarily solves the problem, but I'm worried that I might break it over time.
Has anyone else experienced this, or can anyone offer a tip to permanently fix it without me needing to send it back to Ron?
