I recently purchased a pair of Kahtoola aluminum crampons. Once i adjusted them to my boots they were awesome. Very lite compared to the steel ones I had been using the last two seasons. Very easy to deploy and take off. Very good traction with not a lot of snow and ice build up. No worries about rusting either because of the aluminum. The straps work great with zero chance of loosening up. Overall very excited about purchase. I hike twice a week so we'll see how they hold up.
