I use these on my cyclocross bike so I can clip in for some serious riding or just hop on it in street shoes for a quick trip in the neighborhood. I find the SPD side to be reliable and easy to clip into and the platform side offers a solid surface to use for regular shoes. I also installed them on my trainer so I can jump on it when I have to stay indoors.
I ordered these pedals to ride on snow and ice using my studded tires. By not having to clip in, I have felt more secure using these pedal on difficult ice. When there isnt any ice or th ice is smooth I can clip in and ride with more efficiency. I am very satisfied with these pedals.
I built up a bike this year and ordered these pedals. on my first test ride the pedals begin to make a clicking noise on each crank stroke at the top of the arch. after 10 miles it was really loud. I got back and made adjustments to any thing that looked like it could be connected with the noise. Test ride 2 was even worse. After emailing btd and getting no response I went out and obtained a pair of pdm8000 pedals (from a different source) noise went away new pedals felt great. very disappointed in this model of pedal.
Disclosure I've been a roadie for 2 decades, and only added MTB this spring and this is the first set of lipless pedals on an MTB I've ridden.
I really like these pedals. They were inexpensive, and they work as advertised. I like being able to adjust the difficulty of clipping inout, and the flat side of the pedals is sufficiently grippy. I've never had any issues clipping in without looking, as my shoes seem to easily clip in. My only minor complaint is that I wish the flat side of the pedal were larger. However, that is likely due to having size 13 (48) feet and being new (and less comfortable) riding MTB than road and wanting a wider platform.
Nice pedals but I have nothing to compare to since these are my first pair of clip-ons I like that you can still use regular shoes on the other side it's helpful when you're trying to clip in after you stop and get going you can pedal on the opposite side
