I was told a 100 gram slice would last about 2 months....it’s been 3-4 months and I haven’t noticed it going down much .....so I’m wondering how long a slice lasts you guys? I mean I load for a minute..I soak it for couple mins beforehand...I scrub it like crazy...not complaining just baffled...either I got a brick that is super compacted...or something is going on idk lol...
