I just put my studs on last weekend (I bought them in July!). Tried them out for a short 25km ride on Sunday when the temp was -12C. They worked great! I rode to work with them today with another 10cm of new snow. They're a little squirrelly in loose snow marred by tire tracks, but they're great on hard packed snow and ice. Highly recommended, even if our "winters" only last about 2-3 months. If they prevent a single fall that otherwise would have resulted in an injury, then I consider the investment well worth it.
