I've stockpiled sets of the A600s and have run them for many years. I was excited for these pedals due to the weight and my past experiences with Wolf Tooth products. When I got them, I immediately installed them on my Crux and put them into daily service.
After two or three rides, I was already convinced I could get rid of my A600s. Great engagement, solid feel and good shoe support. I raced them at Mid South 100 and they were fantastic. Getting in / out is fine despite the 1 sided nature, as easy as the A600s.
Durability is still to be determined, but the fact Wolf Tooth offers every single replacement part and stands behind the right to repair I'm optimistic. After a thousand miles, they still feel like they did on the first ride so no immediate durability concerns at all.

I've tried to use cheap off-brand replacement cleats, but they never work as well as the branded ones from Look or Garmin. These engage and disengage perfectly, as they should. The rubber padding on the bottoms is less slippery than the typical, harder plastic. I don't know yet how long they will last. For my typical training, I don't walk around that much. However, when we get into the summer with some long events, I'll be stomping around feed stops where the cleats usually get chewed up. This is also the first time I used the grey float, usually using the red. When it comes time to replace the cleats on my other road shoes, I'll go with these again.

I used Speedplay pedals for many years. I got stuck in them several times-meaning I could not break the cleat free from the pedal because dirt was in the cleat. Not again.
These Shimano pedals are a good value. I can't see ever getting stuck in them. Exiting the pedal is easy.
I don't like how the pedal is alway turned to the wrong side when I try to clip in. I wish they were weighted so the enty side was alway up. (Speedplay you could use either side) Not a big deal but if you are on a race start you would be left in the dust trying to clip in.

As a grumpy old Luddite still riding cabled and round tubed bikes, I was surprised to feel a little frisson of excitement when the single-sided DEL gravel pedal was introduced. As a dedicated Speedplay rider for 10+ years (RIP Syzr pedals), the thought of reverting back to one-sided entry was daunting but not a deal-breaker. Sure, there was an adaptation period, but the brain is pliable and I adjusted after a couple of rides. Right out of the box I adjusted the Q-factor outward to 57mm (using WT's spacer kit) to accommodate shoe size and toe overlap. That, plus the larger platform surface made a world of difference in power output and comfort! Like other reviewers noted, the pedals don't always sit up in a "ready" position. Mildly annoying at times, but not enough so as to detract from all the positives.
