Product review (4 stars): Good product, not quite identical to original filter
The Waterdrop filter cartridge was a direct replacement for the Maytag UKF7003; however, as I've seen mentioned previously, this filter does not have the small triangular protrusions on the top that help hold the cartridge in place. It can be turned easily by rubbing against it, if you're reaching in the back of the fridge, which could result in a bit of a watery mess. I've taken a Sharpie and marked the correct position on the front of the filter so that I can easily see if it is in the correct spot. This would easily be a 5-star product if it had a design identical to the original filters. Still a good value.
