Bottle conditioning in swing-top bottles

[zxr400]

I've been using the PET plastic bottles for my last couple batches but i like the idea of using swing-top bottles. 

after reading some threads like below,  im not sure they are suitable.  Has the quality of the gaskets improved since 2013?

I'm looking at something like these.

I have no problems with mine and some have been used twice so far.

I was told to change the seal after 3+ uses.  Not sure how one keeps track of that though!

I used bottles similar to this that I got from my local bin inn. I have used them for a hefeweizen that I carbed to 3.5 and they're holding it fine.

I have had bad sealing issues ie about 50 % flat and as a result gone to ABC big bots and caps.

I regularly use recycled grolsh bottles, Ive never had a leaker.  I have never replaced any of the seals.

I have about 50 Grolsch bottles that I've been using for over 3 years and never had a leaker either. Sawmill ones have served me well too. I've not had the same luck with those 750ml copper tun ones, about $150 and a fair bit of beer down the drain because of them.
