The suction pads were the best part. the iMac screen removal was simple using them. They are REALLY sticky. I used the screwdrivers, but the handles are a bit thin to get a good grip. It worked fine, but if you already have a set of Torx screwdriver attachments, you could use them instead. I didn't seem to need the extractor tool. I used the cloth to dust off the screen before reassembly.
My old iMac 2011 was extremely noisy, I believe due to the fans control. Since I installed the OWC digital thermal sensor, the computer became super quiet. I wasn't sure this would work but it has done a miracle! It is a bit pricy but is worth every penny, I highly recommend it!
