Product review (3 stars): Expensive, but you can't beat the quality
The good: it's factory authentic. You simply can't beat that. Quality and longevity are spot on.
The bad: expensive, expensive, expensive. Have I mentioned these are expensive? There's really no reason that a filter should cost this much, but they've got you hooked.
There are certain items that you can go knock-off brand on. Unfortunately, this isn't one of them.
