BEST DUMBELLS EVER!!!!
I was torn between these and the PowerBlock dumbells I kept reading about. I had a chance to check out the 2008 and prior model Bowflex Select Tech's at Dicks Sporting Goods, and I remember thinking about how easy it was to spin the dials to adjust the weights.

My only concern and hesitation was that a few reveiws mentioned the possibility of the weights rattling and people were worried they could fall off? I had not heard this before, so I researched it more and although the PowerBlock dumbells had gotten good reviews, I simply could not get past how ugly they were, and the fact that they used a magnetic pin to hold the weights in.

I decided to spend the few extra dollars on these 2009 model Select Techs (assuming any prior issues they may have had were corrected) and boy am I glad I did, they are AWESOME! The dials, in my opinion, are ten times easier than the magnetic pins of PowerBlocks, and these Bowflex dumbells look ten times more fashionable (our gym equipment is on our loft, so yes my wife and I have a style standard). These dumbells are about 15 inches long, but neither of us have any issues with their size (I think the PowerBlocks were only a 3 inch difference anyways).

We are 100% happier we bought these, and we bought the stand from Amazon to go with them also (it is better for your back if you lift dumbells from a standing position instead of from a squatting one). I hope you enjoy your SelectTechs as much as we enjoy ours!

Huge and awesome.
I just got them, and my first impression upon getting them out of the (decidedly ample) packaging was "wow, these things are MASSIVE." They really are huge, in a way you may have to see to really appreciate; they're around 16.5 inches long and they're about 8.5 inches wide at the largest plate, and will have a pretty commanding presence in whatever room you keep them. That being said, they space they take up is relatively minor compared to an actual set with this range of weight, and it's really nice not having to stack plates or slide weight awkwardly on and off of traditional adjustable dumbbells (anyone who's done it knows what I mean).

My second thought was that I was surprised how well-designed they actually are. These guys look and feel like a pretty stunning example of modern technology; sleek and slick despite their size, you will likely not mind that they get looks. I've not seen previous models, but these are really a pretty space-age feeling package, especially once you turn the rubberized dials to your desired setting and lift the bells out, exposing all manner of intricate and refined-looking innards between plates that were not chosen. I really can't say enough about how nice these things are to look at (but i am a design geek, you may not be so impressed or really even care at all).

In use, they are almost as nice - dials turn with a satisfying click, they lift out of their stands smoothly and cleanly, and there is very little wobble or jingling between the plates (definitely not enough to leave me worried at any time that something is going to go wrong). The overall size of them doesn't actually feel like it reduces my range of motion, but it is something I'm always aware of while lifting, so we'll see how that works out. They slide back onto their stands without problem, and there's no awkwardness in setting them down - no waiting for a click, or shifting them to find their intended resting spot. They're then ready to have their weights reset, and you're off doing another exercise in a few seconds.

Overall, they were expensive but I feel like I got what I paid for. Recommended.

Amazing home workout tool
I used the 552 dumbells with my P90X workout and I have to say they made life a heck of a lot easier. It couldn't be easier to select the appropriate weight with these things, and with limited time between excersizes, these were golden. The construction is sturdy; not once did I feel any uneasiness in using them. Even moves where the dumbells were lifted quickly and brought back down didn't cause any issues with the locking mechanism of the dumbells. The only slight issue is the overall length of the dumbells. The width is manageable but the length can cause a few issues in maybe 5% of the excersizes performed. An example of this is doing concentration curls with both arms simultaneously. I ended up having to alternate to get around the length of the dumbell. All in all it is quite easy to work around this small issue and it doesn't impact the 5 star rating for me especially considering that having used the block alternative as well, the bowflex ones caused a lot less issues during excersize movements.
I used these without the stand, if you do as well make sure you lift with your legs and not your back. If you have a bad back, or just want to be safe, you may want to go with the stand. (Though theres nothing wrong with a little extra leg work with the proper form ;) ) In summary, if your doing P90X, or any other home workout routine that requires you to switch weights quickly, this is the dumbell for you. Also if your going for P90X know that the 552 version covered the weight I needed for every single excersize (I'm 5'11' and 195 lean muscle). I may have been able to go heavier on a few excersizes but the sheer intensity of this workout would have limited my reps significantly. Hope this helps!
