Product review (4 stars): Replaced W10190978 and started making ice in a couple of hours -- careful not to break inbound tray when cutting out hole
Ice Maker was a fine fit to replace my original W10190978 which decided to stop functioning and the price was fair at $34.95. As other reviews mentioned, you have to punch out the hole where the water feed is, hopefully you do a better job than I do doing this since I ended up cracking part of my inbound water tray on the new part in the process.  Thankfully the crack seems high enough that it is not causing a problem with water ending up on the bottom of my freezer, but as careful as I was, it wasn't careful enough. Worst case I will have to pull it apart and take the one off of the old unit.  Installation was pretty simple, it would have only taken a few minutes had my ice maker not been so inaccessible with the drawers in my freezer.  Replacement part doesn't seem to have an extra clip, so the wires don't stay in place as well, but it's not that big a deal. Had to reuse the wiring harness as expected and choose to reuse the bottom mounting clip since the prior one was metal and the new one was plastic.  Only had made it through one ice cycle so far, don't have a ton of feedback on how well it performs, but it did start making ice within a couple of hours of being installed. Took off one star because punching out the inbound water hole was really annoying and as careful as I was, I damaged the unit in the process and it is missing one clip on the bottom which the old unit had which held the thermal wire in place better.
