Budget electric grinder only(best bang for the bucks under $100), not for those that are serious and seeking for espresso nirvanas. if budget wasn't an issue, I would definitely buy something else(Macap/Mazzer).
Positive Product Points
i) Cheap, best bang of the buck that you can get out there for low budget ii) Acceptable grinds for espresso (from point of view of a newbie) iii) Great looking
Negative Product Points
i) as what other people said, ground retains. Can be reduced with a bit effort though ii) limited adjustments for espresso

This is by no mean a great espresso grinder.It is acceptable, but not great. So if you have the money to throw around, I will definitely recommend to spend a little more and get a decent grinder for at least about $200, such as Nemo Lux etc. However, if you are on a tight budget like I was (below $100), Capresso Infinity is one of the best option out there.
Pro: i) Cheap ($83 shipped new burr grinder, what more could you hope for?) ii) Acceptable grind particles(pretty consistent to me) iii) Best bang for the bucks under $100 (mind you, they have the best quality burr amongst its league)
i) Fair amount of ground retain (can be reduced by tapping the housing at every single use, I guess that is the price to pay for such a cheap price, I don't mind it though as I cant afford any better) ii) Limited adjustment with just about 16 settings , but only 4-6 of the finest settings are for espresso. You can mod it into stepless, but not without cons(difficult to retain setting).
Conclusion: It is definitely, if not the best, one of the best budget burr grinders out there. I am able to get about ~2 oz in ~25 second using my used Carezza. But the thing is you need to tap it at every single usage to get most of the ground retains out. If you can bear this, it's definitely worth it. There's no static issue for me by the way.
One thing to note, I have never owned any entry-level or pro grinder at $200+. So the consistency and quality seems acceptable for me. You can take my words with a grain of salt as I am still considered a newbie. Overall I am pretty satisfied with the performance so far. I would definitely upgrade if I have got the cash $$
Update/Edit: After 8 months with more coffee experiences, I have more insight than I once had. In my very honest opinion, if you definitely do not want to spend a fortune on espresso or are just getting into espresso to see if it's your thing, I would recommend a Capresso Infinity as an entry-level grinder under $100.
With some easy modification, you could get it to perform very well for espresso. What you're probably missing, is just a very subtle improvement in the taste that all newbies are probably having hard time to recognize (The limiting factor here would probably be the machine's water temperature and your dose/distribution technique, not the grinder), and also the build quality that the higher tier grinder offers. One thing to keep in mind, the durability of the burr will probably go down faster if used for espresso because you're using the burr more extensively. Maybe from 2-4 years down to 1 year+ depending on frequency of usage. So, if you are sure espresso is your thing, definitely time to save up and get a high tier grinder that could last for decades. This Capresso Infinity could then be used for your non-espresso brewing without upsetting your dedicated espresso grinder's setting and this will cover you for all other brewing methods for years to come. Personally, I would rather spend more if I could and get a grinder that lasts forever, rather than changing the cheap grinder for every few years. The cost does add up in the long run.
Bottom line, for the money and the performance return, Infinity's definitely worth it.

Three Month Followup
After about 8 months of getting into coffee, I have had my hands on different grinders and has definitely learnt more about the importance of grinders. I have tried comparing Capresso Infinity with the higher tier grinders, such as Super Jolly, Major, PGC and Vario, it seems that the shot quality isn't that strikingly much better as to the extend of days and night difference, as you would normally read from forum. The taste in the cup are subtly different, the shots from Capresso has very little hint bitter and wasn't as clear tasting as those from higher tier grinder. But, without doing a side by side tasting, I can hardly tell what I am missing from the higher tier grinders. Assuming coffeegeek or homebarista forum doesn't exist and I did not read the how "different" the lower tier and higher tier grinder are(I warn you, that's where and when most 'upgraditis' happen), and if I were to have Capresso Infinity as my only grinder , I would be equally as happy as I am. Capresso Infinity is definitely a capable grinder for espresso and if you can get it adjusted to produce about 1.5-2.0 oz in 27 seconds with FRESH coffee. The significant improvement from lower tier to higher tier grinder, in my opinion, is that you get a easier dialing in experience and a more rugged build quality that can easily last you a few decades. Most of the time, your techniques and also the espresso machine will be the limiting factor here in improving taste if your grinder could grind to ~1.5-2oz in 25+ seconds
One Year Followup
I cant believe it has been 1 year since I've started my espresso journey. Capresso Infinity was my entry level grinder to help me understand the variables and how espresso extraction works. It did well for what I expect it to do. For starting out, I really wouldn't mind going this route again. However, I've read that some people actually can't get their Capresso grind fine enough for espresso. I was lucky enough to have mine to be espresso-capable, but I think there's a work around to get it grind finer. If you definitely can't fork out more than $100 for a grinder, this is one of them that most probably will work with a little effort and patient from you. but if you can squeeze a little more, there're some better alternatives out there.
