I purchased a pair as a surprise Christmas gift for my wife. Unfortunately, they weren't as large as I'd hoped, I had to estimate the dimensions of my wife's current pair which she'd been wearing continuously for more than 20 years, rather difficult to measure without her knowing! Imagine sneaking up on her while asleep armed with a ruler and a torch.

The returns process was very smooth, since they were untouched in their original clear wrapping, with the money refunded promptly. This is good to know when purchasing online. All in all, the whole purchase/refund process was smooth and professional.
