Query: Great Filter, Awful Mount

I'm sure the filter itself is great, but I'll never know for sure because the mount that holds the filter in place is worthless. After about 5 uses is started to leak. I tried to retighten it to my faucet but the plastic threads just aren't strong enough to hold up the heavy filter.The last straw was last time I turned on the water, the whole filter (mount and all) came crashing down into my sink.Maybe it will work better in your sink, but for me it's worthless. Don't bother with this product until Pur fixes the mount.
