I personally own a pair of 'yellow', light quality.I use them for
recreational rowing only. For my purposes they are worth their money.
Our club has some sets of them in 'red', a lttlle bit heavier quality.
Some are used for racing. No complaints so far.

A friend used to sell them in Canada. We used some during a training
camp in Victoria BC and didn't have any complaints. They were a bit
expensive at the time and with exchange rates what they were, we opted
(at the time) for a different brand.
