BUY IT

I am a repeat customer for this product. Some would say that it's a bit pricey but it's worth the extra bucks to get quality/performance that a person should desire......and it's not even the most expensive that you can buy. It's a mid-grade. Filters are like lawyers in that good ones aren't cheap and cheap ones aren't good.
