Rated 4.0 out of 5.0 by LocalGuy Works good, ignore the inexperienced DIYers.
I often find that most people writing reviews shouldn't even be doing home improvement projects...
The light bulbs dim all the way to darkness. I suspect most of them don't realize their light switch has a dimmer adjuster built inside. So when I first turned it on, yes it barely dimmed but after adjusting the switch I could it to pitch black if I wanted.
And of course, make sure your switch is CFL compatible and that its a dimmer switch.
I'll be back to let you know if they actually burn out shorter than expected... if not, see you in 9+ years.

Rated 2.0 out of 5.0 by gcolefla Not as Dimmable as Expected, Not enough info on Package
This is my first set of dimmable cfl's. I purchased a Leviton CFL Slide Dimmer to run a fixture with both of these bulbs.
I was expecting these bulbs to dim from 100% brightness down to 10%, or maybe 25%. However, I would say they only dim to about 40% of their brightest value. I was hoping that I would have a product that could go from bright task lighting all the way down to dim lighting to watch movies. It just doesn't dim that much though.
The packaging should describe the dimmable range or have more information on what to expect from dimmable cfl's. If not on the packaging, than this product page should list or link to more information.
I have purchased some ecosmart cfl's in the past and have been happy with the daylight color, and their longevity. These have the same light quality, but they don't dim quite as expected. These currently cost 4 times as much as the same brand's equivalent non-dimming bulb.

Rated 4.0 out of 5.0 by DGray Solid, but not terribly dimmable
I started by replacing our old dimmer switch with a new Lutron Diva CFL compatible dimmer switch. First, the positive: the lights seem to be well constructed and solid, and they worked fine in our ceiling fixture - at full brightness or at any level of dimming, there was no buzzing, no flicker, and no drop-out. In this respect they were quite good.
The negative: they didn't dim very far at all, not nearly like an incandescent. I'd read that this could be an issue with dimmable CFL's, but I thought a new dimmer that was specifically CFL compatible might help. If it did, it wasn't by much. To put it in perspective, dimming these bulbs did make a difference that was noticeable, but for us, not really enough to change the ambiance of the room at all.
One other note - these bulbs are seriously white. I knew they would be much whiter than a standard soft white bulb, but for us, these were actually too white for a living room. This isn't necessarily a draw-back depending on where you plan to use them, but just make sure you really do want a very white light if you buy these. They would probably be great in a utility room, laundry room, a garage, or somewhere similar, but for a living room I think they tend to kill the warmer atmosphere most people are expecting.

Rated 2.0 out of 5.0 by nitewulf Poor performance
I bought these for my ceiling fan in my living room, they sit inside a bowl fixture so the bright white light is mutted somewhat; I like the effect.
The ammount that they dim however is absolutely pathethic. I also purchased a CFL dimmer switch and quickly found that at the lowest level the effect was hardly noticible. You can tell them they are dimmed, but not by much. I would guess that they dim to maybe 70%. Anywhere inbetween on the slider is hardly noticible, instead of a slider there might as well just be a switch.
I wanted to be able to dim the lights down low for watching movies, these don't even come close to dimming far enough.
What a waste of money.

Rated 2.0 out of 5.0 by Enlightened Heed the review warnings
Save your receipt! Bought five 2-packs because I needed 10 bulbs for my vanity fixtures. One bulb was defective right out of the package. Another quit working in less than an hour. Still waiting for the rest to burn out.
Dimming - The reviews on the dimming are correct! You might get a 30% reduction, but nothing compared to the incandescents (which I placed side-by-side to the CFLs after 2 quit working). And I did have the proper CFL dimmer installed. And no, the package does not tell you that you will need a special dimmer. I discovered this while shopping for dimmers.
Buzzing - Also, the bulbs have a slight buzz - even when on full brightness. I don't think there are any bulbs that don't buzz when dimmed, but these buzz all the time. I think is has something to do with cheap filaments.
Flicker - I have not experienced any of the "flickering" that others have when the bulbs are dimmed, but they do flicker a bit "as" they are being dimmed.
Range - Be aware that if your fixture has upward lights, like so mant vanity/wall fixtures, that the solid base prevents a full 360-degree light, but that is more an aesthetic turn-off than function. With new 60-watt incandescents side-by-side to the CFLs, the CFLs were actually a bit brighter overall - just not as much "downward" light.
I am going to give them a few days to burn out, and then replace the defective bulbs (assuming Home Depot will let me return them).
I am sure the technology will eventually improve - some day the bulbs will be truly dimmable, have 360-light, and they'll encase the piggy-tail like they do some of the non-dimmable CFLs to look like a standard bulb. But right now, they just aren't there.
I would have gone LED, but the structure of the ones I saw is even worse for upward fixtures if you are wanting 360-degree/downward lighting from your bulbs.
I am going to stick it out with these bulbs, but I will truly miss the dimming capabilities of the old incandescents.
