LeFix Replacement LCD Panel Adhesive Tape Strip Sticker + Opening Cutting Wheel Tool Kit for iMac 21.5'' 2012 2013 2014 2015 A1418

I recently had to upgrade the hard drive in my iMac and of course, had to take off the screen and needed these adhesive strips. They seem to work perfectly, but I did have to trim one of them down because they are off just a little bit. But not so much that it made a big deal or a big difference. It would be nice if they were a little more helpful with telling you where to put each one of them they kind of just say starting in the left with one and work your way around, but they don’t really lineup completely. Either way they’re a great value for money and they did the job.

You've got to find the video for the name brand version so you know where each number goes, but dead simple and well made. The little pizza cutter tool came with extra wheels but I only needed to use the one.

It was a perfect fit for my late 2013 model 27" imac; very easy to install and secures the screen well.

If you take your time, this works perfectly fine. Test Mac before closing everything up.Make sure to scrub off any residue from the metal body and the glass case with a towel and rubbing alcohol, maybe even a plastic spudger. This took me about 40 minutes to be 100% certain it was clean.Don't grab the screen with your oily hands all over the edges as that will make it not adhere well.After installing the screen, LAY THE MAC ON ITS BACK!!!Use a towel to press down all around the display.Either use a heat gun from a distance on the front and rear or turn on the Mac and play a high res video on it for a few hours. Maybe use clamps and towel/sponge on the corners. I had it rest like this overnight just to be safe.The 2nd time I took apart the same mac, I cracked the screen (barely visible when on), so I guess the tape works very very well.I would also recommend using zip ties or something to hold down the sata cable to the ssd if that's what you're doing.I had it come off very slightly loose after 4 months, causing it not to boot (flashing folder with ?).

I've been working with and building computers for over 35 years. I will say that replacing the Fusion drive in my 27" iMac was intimidating to me even after watching some YouTube videos of folks who made it look extremely easy. There's something about using a heat gun and scraping tools to get remove a delicate display screen that made me pretty nervous. I will say the single biggest reason why I purchased these strips was the tool that comes with them that you slide in behind the glass to break the seal on the old adhesive. It really is like one of those kitchen tools my mom used to have when making an apple and she had this wheeled hand tool that would poke holes in the crust.That tool made it so easy, once you applied the heat to the glass to just roll along the edges and separate the glass from the old adhesive. Without this tool, it was going to be like using tire-irons to replace an inner-tube on a bicycle.The adhesive strips are the perfect amount of really sticky but not so sticky that they are unforgiving if you have to pull it back up and fix a mistake.I would have given these things 5 stars had they simply included a diagram that explains what strip goes where. Nowhere in the box were any instructions and the strips must go in very specific locations when installing them as they are cut to fit into those exact spaces.I did find a YouTube video that explained where they go but I think a piece of paper showing where each piece goes would be helpful to folks who have not done this before.If there were instructions, this would have been a 5 star review.

I was kind of skeptical due to people saying that they had issues with screens falling off, but I have used these strips on a couple different iMacs and have you even shipped them across the country and they still have held strong. The most important thing you have to do is just make sure you clean the surfaces on the display and iMac very good so you have good adhesion and you should be good.

Perfect fit and very easy to use. The screen fit tight and sealed great!

Little bit tricky but works with 2019 27" iMac
