Rubber Suckers

Do other people have the same issues that I do with the rubber suckers that attach filters to tank walls? Mine fall into two categories, either they attach so strongly that getting the filter out for maintenance is a trial of strength or, as they get older, they lose the will to hang on so that the filter just falls off. I've recently replaced one filter which kept falling off and now another has the same problem, it has four suckers but they have lost their flexibility and all grip. Unlike heaters, each manufacturer has their own sucker design and attachment to the filter so that they seem impossible to replace. More expensive makes seem no different from cheaper ones in this respect. I tend to call rubber suckers by a "sounds like" name .............
Maybe some people have found alternative attachment methods?

I have had a few heaters fail and keep the suckers which tend to all be pretty much the same size.
Otherwise I think the best answer is to buy heater guards that come complete with suckers, they are very cheap.

My suckers either fasten themselves to the glass with a vice like grip and can only be pried off by me sliding a nail under them OR they just fall off...the clear plastic suckers seem to have the least grip

My tank is on the slightly acidic side of neutral, so all the suckers I've had (except for those on my heater) have degraded over time. Soft ones get pitted and plastic ones go rigid. I have no idea why the heater ones have survived. Unless they're more hardy to cope with the heat.
