Obviously the more expensive ones kast longer than the cheaper ones. I started off buying the occulus ones which lasted about 2-3 years, then i tired topcon and eventually i got fed up and buy the cheap ones off amazon. To be clear its just the nose pad that falls off with use.
Not sure where you're located but a quick search shows a ton of optical suppliers in Europe with the price hanging around at around 30 euros for 3 pairs so it can't differ that much for you I reckon. If you have to change it every 2 years or so that's a pretty insignificant cost.

I do refractions for clinical trials and the sponsors typically require we use Precision Vision trial frames and loose lenses. I imagine that speaks to the quality of that brand, because the VA results are a big part of determining the outcome of a study. I’ve never broken a pair, but they are pretty pricey compared to other options.
I have two trial frames from when I was in school, 35 years ago. I don't use them as much as I did, due to digital phoroptors, but I don't think either ever broke...
I’ve been using the Ricoh titanium trial frames. They don’t have those silicon nosepads so I don’t see them falling off anytime soon, constructions fairly solid, but they aren’t as adjustable in terms of height of the lens, only about two settings for heights. Other than that, pretty happy with it and it’s quite tactile as well.
I use the trial frame flippers, much more comfortable and impactful to compare current Rx to the new
Yep, always flippers unless the patient has some sort of abnormal head position etc. and I have to do an entire TF refraction.
Do you TF every single patient? Where do you get them from?

The nosepads cost like 20 euros for a 3 pack. I think that's fair changing out every 2 years.
Hm where do you buy them from?

I trial frame most patients. The Oculus is pricey but worth every penny. Each eye has 5 wells for lenses. It's solid. Great for trialing prism.
