Hmm they dont mention if the Spiedels are made out of PET plastic. Thats a concern
I use buckets myself but I see a lot of folks bemoaning the sucking airlock. I just wanted to point out that if you use the 1 piece airlocks (S shaped ones) this is not a concern as it will just bubble backwards.
If all it is is sanitizer in your airlock, I don't see the big deal. I'd rather have sanitizer sucked back than air.

If you need a good degree of gas/oxygen impermeability then PET is the way to go.As far as the airlock sucking when you lift a plastic carboy, I deal with that by just replacing the drilled stopper with a solid one before picking it up.
