don't listen to the reviewers
crazyaaron1984April 24, 2015
Pros
there is no such thing as a "custom install" on the installer... if you people actually paid attention to the installer you would know this! also it's an evaluation "free" version, the company wants to make money by making it limited and encourages customers to get the paid version. also, if you know how to use this, it is useful. unlike the reviewers here. if you don't know how to use this software, USE GOOGLE!!
Cons
it is limited but still useful for the simple thing it is intended for.
Summary
thanks to the company for creating a software that makes the process easier than how windows has it currently
don't even bother

Pros
it was simple to install except make sure you use the custom install
Cons
the evaluation was worthless....don't waste your time or money on this
Summary
Not Free, Didn't work for me.

Pros
Looks nice.
Cons
Had a LAN card with all Zeros for a Mac Address. Using this I made a random address and restarted the adapter. Still didn't work and it wouldn't connect to router and ethernet. Used a free program Technitium and it worked great the first time.
Summary
Works well as intended

marcelogeekOctober 19, 2011
Pros
None, because after installation requires payment
Cons
Could not use it because it requires payment upfront. IS NOT UNLIMITED TRIAL
Summary
keep looking
Useless and not worth it
ekwatiNovember 15, 2009
Pros
Unable to try it
Cons
I didn't get the chance to try it as they force you to use a specific MAC address
Summary
I will search online for other applications that do the same thing. This has been a major waste of time installing this useless application.
Tried SMAC 2.7, works great on VISTA & 2008.
bah1234April 1, 2009
Pros
Tried SMAC 2.7, works great on VISTA & 2008, both English and non-English OS. SMAC 2.7 made some improvements for non-English versions of OS. GUI is neat and simple. I use it all the time when I'm on public wireless wifi.
Cons
Nothing I can think of at this time.
Summary
It works. It has made my life easier and more private when surfing the public wireless network. I have tried others but still think SMAC is simpler for me. SMAC was recommended to me by a couple of colleagues and a relative, and I am happy with their recommendation. I have used SMAC for over 1 year now, and I'll say SMAC 2.7 is more straight forward for VISTA and 2008. I use it on English and German OS without any problems so far. It is pretty solid software.
Works great!

Pros
What can I say, I ran SMAC 2.7 Beta and it works great on my VISTA 64.
Cons
none so far.
Summary
Works like a champ! Got my wireless privacy now!

Pros
Work like a champ! Made in USA Support is great too Awarded by PC World in 2007 Largest user base for MAC Address Spoofing software I use SMAC to spoof my MAC Address to protect my privacy when surfing at Wi-Fi Hotspots.
Cons
wish it's free but got 20% discount with coupon code SMAC5Y, so can't complain too much. Worth it.
Summary
I like it. Free to try, but worth the money for Standard Edition. Look for Coupon code on the web to get some discount. I used coupon code SMAC5Y and got 20% discount! :) I heard it has been used by many Fortune 500 companies and government so it got to be the best.
"No Limitations" is a lie.

Pros
Cons
Yeah, it'll allow you to change the mac address, but the evaluation version only allows you to change it to a mac address they specify, not one you enter yourself.
