Well 3.x was great, but not 4.x and certainly not 4.x Pro. Firstly let me say, I believe that the Iolo inclusion of security software to their product, particularly a less than the best . . Panda . . is in my view a bloody con. Nowhere until you are well into the install is there any mention of Panda Antivirus software, then all of a sudden you are told, 'if you wish to install the Panda software, please remove all other antivirus programs from your computer' . . . oh yeah!!! Like hell I will, not when I have taken great pains to test and install what I believe are the best security progs. around . . . (Sygate, Avaste32, Spyblaster, Antidote - all free)Panda leaves a lot to be desired in my view. But the nerve of Iolo to expect me to remove all other security software! Well, apart from that, the defrag appears to be flawed, as it has hung on several tries and yet my old and faithful Nuts & Bolts defragger chugs through with no trouble. I don't want an unreliable defragger - I get nervous enough while defragging. I don't believe there has been any serious attempt to improve most of the tools, they all seem pretty much the same. I feel that what was good and reliable, has not been improved. My view is, until Iolo decide on a major upgrade and tell the consumer what changes have been made, and not conceal tricky things, they know where they can shove their toolbox. My verdict . . stay with the 3.x version - there is an update available now - 3.8. Esra (Pent 350Mhz 128mb Win98 2ndEd)

Becuase I thought SysMech5 was good and Kaspersky AV/Firewall is updated many times a day and catches things Norton does not, I tried SysMech6 and wished I had not from Day one. SysMech 6 Pro is a complete disaster, as might be inferred anyway from the fact that they have issued 21 revised versions to the original release in late 2005, the first seven or eight of them within two weeks of original disastrously inept release. SysMechPro6 crashes frequently, locks the system, overrides user preferences when doing Total Care, deletes items without giving you the option of canceling the deletion, is slow on clean and defrag, inaccurate on Memory defrag [often requiring a dozen passes till it finds the right final point), and requires frequent non-optional system restarts. Moreover if you run the same utility twice in a row it will "find" errors the second time that it did not find the first time and after some utility actions it will then analyse itself again (non-optionally and slowly) and report that this new post-operative analysis has now found errors and you have to run the thing again. I don't trust the program any more and when a Program gets to Version Issue T in the space of less than 9 months you know the programmers have made some huge and worrying errors in the earlier versions. I now won't upgrade any Iolo products until I have read many reviews first. Also as noted in other reviews their "Support" is rubbish. Do NOT purchase SysMech6Pro. It is ... UNprofessional.

Ran System Mechanic and now my PC will not produce any sound whatsoever. The worst thing about this is that I reported this problem to IOLO support and was completely ignored!!! IOLO does not even have the common courtesy to respond to my email. I am not a novice computer user. I used System Mechanic to back up the registry before running it. The restore of the registry did not fix my problem. I still have no sound from my PC. I realize unusual things can happen with various PCs, but the fact that IOLO chooses to ignore potential customers is amazing. It shows you the type of support you would get AFTER you paid for one of their products--nothing.

Seemed like a solid product ... I downloaded the trial version and all seemed well until I PURCHASED the product. Then I find out that the antivirus and firewall software is from another company, Panda. I have yet to be able to successfully register the Panda software. Panda's support is worthless at best and refused to assist. They then wanted money to further help. Iolo was no help either, but at least their technical support was professional in telling me "not our problem". Relegated to the "wish I had not spent that $69.95" pile of useless software. Oh yeah, this software has never successfully defraged any of my drives.
