Product review (5 stars): GE quality.  Just make sure you know your model number of your fridge.
This unit was easy to install, all the parts were of good quality and the directions are clear. Only bolt-on parts and plug-in electrical. All I needed was a phillips screw driver and adjustable wrench.  It's easiest if you can get good access to the full backside (top to bottom) of your fridge.  All the plumbing is in the kit, so you don't have to worry about cutting into your fridge's electrical or cabinet.  Getting the water supply line connected into your house plumbing can be tricky, but that's not part of this kit.  Just make sure you have the model number of your fridge / freezer before you order and before you begin installing.  Parts are supplied for many various refrigerators, so you need to be certain you identify the correct parts to install. (The variations are very small.)  Don't worry, it's fully reversible. There are about 12 sets of instructions, each one is for a different variation of your fridge. Just pick the right instructions for your model and you should be up and running in about an hour.  I easily added an inline water filter (Tier1 GE GXRTDR comparable) outside the fridge for good tasting ice.
