I can't speak for the differences in these replacement keyboards, if there are any, but this one feels excellent. I had considered another kit, but would have had to buy screws and the backing separately. The description is a little confusing. The LED backlighting is in the keyboard, not the black sticker. The sticker acts as shielding. Some people in the videos reuse the backing sticker, but I would just start over fresh. Plus, you do need the screws regardless. This kit has everything so I went with it, even if another kit seemed to have a more convincing Amazon presence.After installing it, I feel like I should have done the job sooner, but I waited until I had to also do a battery swap. The new keyboard types very nicely. Time will tell if it lasts, or has the same issues of the original Apple butterfly keyboards, but so far it feels better than the original. I mean, it's an 8-year-old machine that I use as a beater for teaching. I kind of got used to how bad the old one was, between a space bar that wouldn't work much of the time, and regular double strikes, but switching back and forth with my newer 14" MBP, it got to be too annoying. I really can't say enough about how much better it feels to type on this after the repair. If the repair is within your capabilities, then by all means, schedule a day and do it.That said, I don't think most people have the skills to do the install. If you have skills and want to take on this repair, and feel comfortable taking apart these machines, it is doable, and there are videos online, but do understand it it is not an easy job. It involves removing every single component of the computer, including the battery, and physically breaking out the old keyboard, wiggling out the old rivets, drilling a lot of .5mm holes and gently installing .6mm screws that are prone to over-torquing and popping the heads off. If you are not well organized, don't have a good works space, and aren't comfortable with drilling very tiny holes and gently torquing very tiny screws, don't even consider doing it. If you haven't done something like this before, you can be patient, go slowly, take pictures, have a very good organization system for parts and screws, take breaks, and in my case, it worked out well.A few of the rivets refused to come out cleanly. The best method was to gently grab them with small flush cutters and wiggle them and they pop out. For me, the hardest part was drilling something like 60 .5mm holes. Bits were broken. One hole went through the top case, but it's not a big deal. A couple screw heads popped off. You will experience similar issues the first time doing this repair, and they are no problem. If you get most of the tiny screws in place, the keyboard still feels solid.My only complaint about the kit was that it needs more of the tiny screws. I ended up having to order an extra bag of screws, not to mention the extra sets of micro miniature drill bits.
