We recommend OWC 2.25" Suction Cup (Mfr P/N: TOOL225SCUP) from Other World Computing for $3.80 as a suitable alternative.
The How To videos from the OWC website are awesome.I would recommend this item to a friend!
When it was time to replace the hard drive on my children's iMac(2007), I was happy to find the suction cups available on OWC. I was a little nervous about the install but the installation videos on OWC were easy to follow, even though they listed the hard drive install as involved. I was able to replace the hard drive easily and saved some money and time on the install. This past weekend I had to replace the hard drive on my iMac and the suction cups were used again.
I also purchased the NewerTech 14 piece toolkit and these tools made the jobs of replacing the hard drives a lot easier.
I am so happy I found them here and would recommend them to any owner of an iMac that is out of warranty.
If you are a mac user OWC should be a first stop for any peripheral or replacement part purchase. The times when I have spoken to presales representatives, they have been informative and have always been happy with their recommendations. I have been shopping here for years and expect to continue in the future.I would recommend this item to a friend!
