I liked the price and I had a very specific application in mind. I had to replace the O-ring in a Nathan's hydration pouch. I measured my needs and requested 5/16 ID, 7/16 OD. I was surprised when I received them in the advertised 1/16 thickness, but they didn't work. I removed the caliper and some o-rings are only 7/128 thick. This difference of 1/128 allows a leak to occur. You can see the light shining through the 1/16mm caliper gap with the ring in place. If accuracy is important, these are not the o-rings you need. Some rings look closer to 1/16, some don't. I gave one star for value because given the sizing issue they are worthless. I bought washers of the same size from the "Big Box" store and their O-rings 5/16 ID, 7/16 OD, 1/16 measured consistently and worked great.
