when should I use the new one, the silicone color is not clear any more(faded and yellow)?

I don't know if the "faded and yellow" is a problem or not, but I replaced mine because the little slits were ripped causing the bottles to leak.

I'm unsure. I had another/original media in the filter, and I just changed this one. So, it hasn't been in there long enough to know what happens for changes in color.

Mine has always been "darkish" yellow. I have been a repeat user for two years now.

Mine was replaced due to yellowing of the bumper part. I had the clear bumper. A colored one might not show discoloring.

It's clear and looks great at first. But over time it will turn yellow. I've had two and both have turned yellow (looks dirty) Cleaning does not help. I won't buy another one.

I loved mine for years,but the plastic turned yellow and is now unattractive,so I am replacing mine for that reason. Still works tho!

I have the same issue once it gets dirty you have to switch out the silicone shell. Other than that it's great!

try using the conditioner that came with the package and leave it in for a long time. the highlights seem to fade fast, so in a few daysit will look fine

ours was pretty wrinkly when we got it..i suggest to keep it up for as long as possible, ours eventually got better.but yours could be worse..if it looks that terrible,i would see if they have a good exchange policy or not...or u could wait it out and see if it gets better.?

When I contacted support I told them that the yellowing was reason I was contacting them and they said no problem. I got my new case 2 days later. So I would have to answers yes to your question based on their action of replacing my case.

try shaking the can prior to use, if still discolorations, I'd call Amazon to discuss.

Mine was blue but I have no idea if it's random or what. It's also not dishwasher safe. You may want a silicone one if that's something you need.

Absolutely it starts to look yucky yellow! I've always cleaned it really well after use its only a few months old and is stained yellow.

If it is evenly grayish, I would be inclined to think it is just discoloration. I wash mine in the dishwasher and don't have any of that. Mold would get worse. Just keep it clean.

I have no idea? Google the company and ask them. Mine looks brand new still.

I have never had one delivered to me that way but I will notice that once over time the lotion on the sides will get slightly tinted yellow. I would ask them to send you a new one. Maybe the seal wasn't that tight.

It's probably just hard water stains. Mine started to turn a bit yellow and running some water with bleach through it for about 20 minutes fixed it. If you try this, be sure to run plain water through it at least a couple of times afterwards to get all the bleach out as I can't guarantee that bleach won't damage the materials that it is made out of.
