Product review (4 stars): Caribbean Appliance goes Above and Beyond
I chose this rating because 1) I haven't installed the product yet, but it is the right part, and 2) Caribbean Appliance went over the top to make sure I was satisfied, so they get 5 stars from me.

My son broke this actuator off of my buddy's refrigerator right after Christmas, so I ordered a new one through Amazon/Caribbean. The part came and the package looked the right size, so I never thought to check it. The part was on my workbench for 3 months until I finally coordinated an evening to go fix my friend's fridge this past Friday. You can imagine our surprise when we opened the package to find the wrong part inside :)  No matter - I contacted Amazon to let them know what happened, and the correspondence was routed to Caribbean who, even though we were slightly past the 75 day period, sent out a replacement part immediately. I have it today, even though I probably won't be going back to fix it for a week or two.

Amazon: You have a good mechanism for resolving 3rd party vendors problems!
Caribbean: You have first rate customer service, I will order from you without hesitation in the future - thanks for the no-hassle swap for the right part!
