Product review (4 stars): 1 O ring vs. 2 O rings. $10 vs. $40. Is it worth the risk?.
Not sure how you can love (5 star) a water filter but it is working and not leaking , knock on wood. The main difference from comparing this to the Samsung is the Samsung has 2 rubber gaskets on the nipple part of the filter and this has only 1. I guess as long as the 1 gasket on this is securely in place and seals perfectly there shouldn't be a problem. However, what keeps water or any fluid from leaking when rubber gaskets are used in anything from filters to cars engines, is the actual gasket. So if the Samsung has 2 gaskets in a row and this has 1, clearly the Samsung is the safest bet. I can't figure out why they wouldn't use the same amount of gaskets since the cost of a small O ring gasket couldn't possibly exceed 1 cent is ludicrous. You can see when they are side by side that the only clear and obvious difference from the outside is the O rings or ring, why not just add the second one for safe keeping?. I guess there has to be some kind of logic but not sure if it's USA logic/Japanese logic/Korean logic orrrr Chinese logic. Probably the latter I would bet about %99. The point is, 2 gaskets are better then one but $10 is significantly less then $40 or $50 so I'll see how this works and as long as the single O ring keeps water in and not out then I guess this is a good buy. I'll follow up at a later time. It's been a few weeks now. Crossing my fingers.
