So I have 2008 390s and got them new last year. They seem very durable and still do after replacing parts but it's starting to get embarrassing when all my friends are riding unions and are not having issues and I am having so many.
Last year on either my 14th or 15th day the ladder for my toestrap snapped probably due to cold weather (not that cold). customer service was very friendly and sent me a replacement quickly. This year on my 2nd day of the season (their 27th day), the left buckle/ratchet on the left anklestrap broke(still works but takes longer to release - manageable since i ride regular and don't go in+out of my left binding much). 2 days later the ladder for the right toestrap snapped before i even did 1 run. We'll see if they send me replacement parts again but i had been looking for a new pair of 390s, and now am wondering if i should try the supposedly bombproof unions.
Manufacturing defects happen all the time and I think you just happened to pick up a pair of bindings with them. Anyhow, if you're not happy with the reliability of your current 390s, why pick up another set?
ive had my 09' 390s for a season and a half how with 30+ days and they have never given me any problems. i too am wondering about the god like praised union forces myself. i want to try them as my next set of bindings but, i love my 390s. so far, my 390s are holding up really well in relation to all the abuse i put it through.
sucks yours are falling apart here and there. might be a defective like the other poster suggest.
you're not stepping on the ladders right? i had 3 sets of 390's and only had an issue with one and it was my fault. i snapped the discs because i ate it hard off a jump. other than that, it's been really good to me. just could be bad luck.
Unions durable that's a good joke. Shit breaks you have to learn to suck it up. Everything you're describing is typical use and abuse do you piss and moan when your car has normal wear and tear issues?
