I have had it for 3 years. Dog. It fits a XXXL helmet and a smaller one, my daughter's. If I remember correctly, it couldn't fit two large ones for a bit. I bought it for 40€ and I never regretted it.

It was purchased for 40 euros to replace an older tec 46lt suitcase. However, if you put them side by side, they have a minimal difference in size, ranging from 1 to 3 liters. This means that either the tec is bigger than it claims (unlikely) or this one is smaller than 52lt. Therefore, I conclude that the manufacturer exaggerates the liters in this specific case. In terms of quality, it is great for its price, but I don't know about its durability yet because it has just been installed.
-1 star for the above reason because I wanted a bigger suitcase than my previous one. It comes with its base and fits perfectly on the rack of the Sym Citycom with a small modification.
