I use these straps every day for my Fitbit but after 3-6 months of use they tend to break on the plastic part where the pin connector goes. I've had three breaks this way just because of the daily stress. I just reordered to replace the broken band I was using (left side in picture) and found that the new ones shipped ALREADY broke in the same place as my old one. in (pictured right) Some of them have lasted long enough that the price might be worth the risk in some situations, but all three in the first pack I bought broke at some point (one every few months) and after the new ones are already delivered broken I see that this is a systemic durability/quality issue.
