Query: Rollers won't stay in!

Absolutely awful product - who designed this? The rollers are too heavy to stay in with the flimsy pins, the pins won't fit around rollers with HAIR on them, and you constantly have to fight to get the rollers back on their "plugs" in the case. The size is perfect for traveling, the rollers work if you have enough scaffolding but it is a complete pain to use - buy something else!
