They are affordable, work very well, are reliable and they give you access to great light modifiers without breaking the bank. They also have some very cool tools at prices you can't find elsewhere, take a look at their CyberCommander as an example. An amazingly useful wireless control system for $179.
There are snobs in every field be it cars, computers, photography, etc. If it's not a big brand name, it's garbage. Are Bee's flawless? No. But tests I've seen have shown that the Bee's are about 96% consistent in their power output whereas units costing 4x's or more are 98% consistent. If that 2% is worth $800 or more to you, buy the more expensive units. For pros this might be an issue. For the average photographer, such as myself, it's not an issue at all.

I've used 2 B800's and a single B400 for over a year now and have shot plenty of modeling gigs, even for a local clothing line. And guess what? No issues with light consistency or color shift. Check out my port, everything in there was shot using Bee's. If you can find fault with the quality of light in any of my images, please point it out.
Bee's are very popular, I see them everywhere. Some have claimed in the past that Bee's are so poorly made that they couldn't stand up to being rented. I think
this proves that notion as being inaccurate. I've dropped by Bee's on concrete while on location and nothing happened. I don't even carry them in protective bags, I just toss them in the back of the Jeep and go. I've used them everywhere from abandon buildings to the beach and they've not failed me once.
I'm on the waiting list for the new Einsteins. These new units promise to be some of the most advanced lights for under $500 a pop on the market with full integration with the CyberCommander system. I look forward to testing them out.
Also, the warranty is top notch. If you're hesitant about buying Bee's know that PCB stands behind his equipment 100% with the best no BS warranty I've ever seen. There's a reason Bee's are so insanely popular, it's because they are a great value and they perform quite well.
It boils down to this:
If you have the money and can afford something like Profoto, get them. I would say most hobbyists don't have that kind of money laying around to invest $8k into lighting equipment when they have a $500 body and perhaps $800 in lenses. If you're interested in jumping into the realm of studio photography, don't feel compelled to buy the most expensive lights there are. Bee's offer hobbyist and yes, professionals (lots of them in use by people earning a living with cameras), quality light for a fraction of the cost. They will work for you, period. You won't get them and think "oh man, these suck!". You'll get them and think "I'm glad I bought these".
Now, if you have the disposable income and or you have the need for the best lighting equipment money can buy, by all means I wouldn't try to dissuade you from buying from one of the top European brands. You certainly aren't going to regret buying their stuff from a quality standpoint. It's VERY nice stuff.
I could buy Profoto if I wanted to. I've chosen to go with Bee's. Initially it was because I wasn't sure how much I would use the studio lights. I stick with Bee's now because they give me everything I want. If they didn't serve me well, I would toss them and go with Profoto in a heartbeat. Right now I'm planning to upgrade my flashes to the new Einsteins. I could easily take that $2k and put it towards a new Profoto setup, but I honestly have no desire to given my experiences with the Bee's. I really like them.
