Have the MC. Takes awhile to heat up. I use it for glass cleaning only bc that attachment works well (and it really does do a good job of that...no streaks) but otherwise, you may be dissatisfied with the steam output...tends to get too cold and steam isn't powerful enough for my liking when you have any attachment on it. If I could do it again, I would've saved my $100 and waited awhile longer to invest in a vx5000 or comparable machine, and done without the steamer for the time being. Just my opinion.
On a sidenote:
1) even with low steam output, it is useful for door, trunk and engine jambs,
2) The MC can sort of be used as a replacement for an air compressor for blowing out crumbs (provided they're not sticky/melty in which case the steamer would melt them into your/owner's carpeting),
3) I used mine to remove old, peeling window tint from an 80something jeep renegade. I don't know what I would've done had I not had the steamer...sprayed some windex under the tint, let it sit, and used the steamer from the center outwards. Worked wonders.
4) Can help in the breaking up/agitation of spots in carpeting
5) thought it would be good for alloy wheels....alas, not.
Overall,
for me, a Type A personality, the steamer takes far too long to heat up, sputters sometimes leaving annoying wet marks (even tho I use distilled water) and is more cumbersome to carry around the car with extra wires etc (I have gravel driveway tho) Add that it't not too powerful and my feelings towards it are lukewarm. HOWEVER, that being said, for $100, from a "bang-for-buck" rather than wholly qualitative standpoint, the MC is a pretty good deal, if you're willing to compromise a bit, and can be useful. Whether or not the +s outweigh the -s for the cost is a personal call! P.S. - Look for Harbor Freight 20% off coupons online/in car magazines too. Hope this helps.
