I Expected More

I have been a Fiblab customer for years and I have found their Memory Clean product very useful. I have a tendency to have many apps and windows open at the same time and Memory Clean comes to the rescue. I suppose that I was oversold on this product.. I have been attempting to leave some wiggle room on my MBP’s 250 gig hard drive and I am very vigilant in emtying all hard drive hogs. I read a review here indicating that I would get “tons” of space back. That sounded good, but I got only 3.3 GB back. My idea of “tons” of space would be more along the line of 10 to 15 gigs. Sorry, but this isn’t for me. I wanted to clean up my current drive before migrating to a 500 gb SSD. Disk Utility indicated that I have a few corrupt files and I would like to remove of fix them before making the switch.

Almost Too Easy

The new interface is excellent. It allows the user to view individual files and check each one off BEFORE deleting them or select whole groups of files for deletion. It even prompts you to make a Time Machine back up prior to making the final deletion so that if you've made an error you can reinstall any mistakes you've made. Great job guys! This was the money well spent for a program! If you follow the directions (fellow men listen) you can’t go wrong! This app gives you almost every option you could ask for and remembers all you’ve selected from the last time you used it. I tink the few the rated it less than great didn’t read before they clicked and hadn’t made a backup using time machine or some other program. I love it.

Get ready for constant ads for other FIPLAB products

If you get this or any other FIPLAB product you’ll also get neat little (GIANT) ad’s for their other products anytime they want to give it to you. I own several of them sadly and I’m not going to install any of them on my new mac for this reason alone. There is no option to opt out of these ads and it comes without warning when the programs open. These products are OK, but nothing magical and not worth this. I also suspect half of these reviews are fake hype since nobody has mentioned this for a while and a year or so ago a review like this was not alone but now they are buried by glowing reviews. It’s gotten worse and I’m done with it. Lastly get ready to buy this over and over again as they make tiny improvements along with a new fancier name in order to re-sell you the same stuff (remember extreme memory clean anyone?)
