How to stop making stupid purchases: The 2M Easy Click clamp for dumbbells

The 2M Easy Click is a closure for threaded dumbbells and looks like this:

It replaces the usual star fasteners that I used to use.

I use the closures for two reasons:

1. The reason the guys at 2M Solutions are promoting this is that the click mechanism allows you to slide the cap over a large portion of the thread before you have to screw it in. This works great and is especially noticeable if you have to reposition the weight frequently.
2. They're made of plastic and quiet. I train in the morning while my family is asleep. So I train with concrete-filled plastic weights and use the click-lock system, which is considerably quieter.

There are no complicated tricks or things to consider. They're simply practical and clever closures that are better than my old ones.

I've been using it for a few months now. At first, you still have to get your bearings before positioning the cap so that you can slide it over the thread. But that's the thing with all new things: you have to learn a bit.

The workmanship seems solid to me. I can't complain.

Of course, I don't know if the clasp will wear out over a few years, but I would be rather surprised if it did.

If the inventors hadn't sent me the fasteners, I wouldn't have thought of buying them myself. They cost 13 euros. That's just as stupid of me as my previous attitude of always wanting to use free software. For example, I used to be content with free, but less well-programmed writing programs. At some point, I realized that was stupid. After all, I write every day, sometimes for 10 hours. I've now bought a few writing apps, just to test them out for a longer period of time. For me, that's not a waste of money because it can improve many hours of my day.

I currently train with a barbell 5 times a week in the morning and a few times during the rest of the day. I estimate that these collars save me about 30 seconds per workout (not to mention that they are significantly quieter, which is particularly important to me personally). This is low for me because I hardly ever move the weights. If I were training with dumbbells or using other training methods, it would be considerably more. Let's assume I saved just 30 seconds five days a week. That's just over 2.5 minutes per week and just over two hours per year. Even if I only used these collars for a year, it would still be more than worth it. Or are two hours of my life not worth €13 to me? Would you buy two hours of my life for €13? I would.

A lot of time goes into such small optimizations when they affect something you do frequently and regularly. And a lot of quality of life, too. I estimate I've spent around €200 on all my writing apps. My current app, which I'll probably stick with for the next 20 years, only cost me €30. But it would certainly have been worth €5,000 just to experiment.

So if you regularly train with dumbbells with screw caps, the caps are definitely worth it.
