I've bought maybe a dozen of these spikes and use to recommend them. They tried to fix the issue of the crampon chain tearing out of the lug by reinforcing the islet. Now instead of a fix-able lug rip (carry zip ties to reattach to the harness, The Whole Harness Rips In Half! Makes the whole system useless.
Tried getting them to live up to their warranty by sending for an RME and following up with phone calls but no response after 2+ month of trying.

I've been using these spikes for 8+ years now and wouldn't recommend any other brand. These are so easy to put on and give amazing traction on ice/hard snow covered trails. I will not go on a winter/spring hike without these. I have 2 complaints, the first is that the price has doubled since I bought my first pair (I blame economics) and the second is that I've broken 2 of these already. I think the durability problem is more my fault because none of my friends have has problems. It's mostly likely from me kicking into hard snow instead of just walking on top of it. But as far as traction and ease of use goes, these are the best you can buy.

I had bought a pair of Kahtoola micro spikes about 3-4 years ago - and had absolutely loved them. i read other reviews saying the quality of the new Kahtoola spikes had changed for the worse, but decided to get them anyway. I got them and should have followed prior reviews more closely. The quality has certainly dropped quite a bit since I purchased my last pair. The rubber is much more flimsy - which makes them much harder to put into my shoes. Knowing what I know now, I probably wouldn't purchase these again. Hopefully, they will improve the quality on future versions.

I like the idea of the spikes. They have great traction on the hardpack. Unfortunately, putting them on for the 4th time I noticed that the rubber on one of them had split 3/4 of the way through. I am returning these ASAP.

Returning these as one broke the second time I wore it. I was excited to have them as heard great things about them, but was very disappointed.
