I have worked with a wide variety of solid kettlebells. Most of them have come out of Russia, but I have also trained with Polish, Hungarian, and Czech variations in addition to kettlebells produced in England and Germany. The one thing that I appreciate the most about kettlestacks (adjustable kettlebells) is the greater distance between the portion of the handle which you grip and the core. This distance is greater than any of the bells I have worked with so far, and means that there is no danger of having to let the wrist fall back even the slightest bit to avoid the ball (core) hitting the back of the wrist. With the stacks, you can even flex your wrist slightly forward and the core will still be on your forearm where it belongs, and not your wrist. In addition to that, the stability of a k-stack is superb, and adjusting weight is easy. Instead of having 12 kettlebells filling my living room, I could have two k-stack handles and a pile of plates and be good to go. Kettlestacks cover the spectrum from 10 kg to 48 kg (less than 1 pood all the way to 3 pood) quite perfectly as well.Excellent product, and excellent product knowledge from the provider!Highly recommended.

I was curious but skeptical about bying the Kettlestack. After a month, it works fine, feels nice and solid and I get to choose the weight. Thanks for your product, I'm sure others will come around and appreciate it. FL, Connecticut
I have always enjoyed doing snatches and cleans and the kettlebell versions are quite explosive, closer to competitive movements than I have felt with pulling and pushing barbells and dumbbells. It (kettlestacks) is an amazing supplement to the practical old school barbell and dumbbell exercises that wrestlers, field athletes have always incorporated into their training. The thick handles are a bonus for gripping strength, no straps needed here.
Varying the weight is very fast and simple as you advertised and there is no worrying about anything breaking on a missed pull or push. I controlled dropped a 105 pound one arm repetitive kettlebell clean on a missed 4th set. No damage, no problem, Next set, all set to go. My friend spent a couple of hundred dollars for a set of quick change dumbbells and they are not made to be dropped at all. Let's just say he is lucky that his father is a welder.
No adjustable dumbbells on the market today with cheap plastic parts can match these tough kettlebell handles using solid steel plates.. Simple, tough and practical. Who could ask for more? Undersold is an UNDERSTATEMENT on your marketing. I have the Mike Mahler kettlebell DVD . The Kettlestack kettlebell handles and his DVD are a killer combination. DW British Columbia, Canada
The main advantage I see from adjustable kettlebells is "price", in a sense of the word. I have four kettlestacks (www.kettlestacks.com) and they function as a complete set of kettlebells from 10lbs up to >100lbs. Some people will say there is an advantage to progression, and that the large jumps in traditional sizes are a disadvantage, but I don't see that as an issue, for the most part. Varying the resistance by varying the sets reps works just fine.
Price flexibility is the big deal to me. Depending on how I want to work that day, I can adjust the kettlestacks to what I want to do (it's easy, doesn't take much time at all). For example, any given workout I can use (2) 1-pood, and (1) 1.5-pood and (1) 2-pood, or any other combination of the above, or go higher or lower than the above in any combination. Buying the four stacks and all the standard plates set me back around $300, but I have a complete set of kettle bells, 1, 1.5, 2 and >2 KB's. I agree with an earlier post about not throwing adj KB's. That's a disadvantage if and only if you plan to do throwing movements. Also, I can use my std plates that I bought for my kb's for my std dumbells.
As for the type of adj kb's, I looked into many and settled on the kettle stacks as my choice. I called and talked personally to USA Ketlebells and kettlestacks and was just more comfortable with the durability of the stacks, but they were both helpful and very polite.
The only thing I can't comment on is the "feel". That's a bit esoteric to me anyway. I get a great workout with the adjustables, and thats what I want. The only real reason I want to someday purchase dragon doors is to support what I think is a fine institution. But for me, I couldn't afford the full set yet, and I'm sure Pavel would rather have me working out with adj kb's than waiting to buy his, especially since I suppory DD by buying his books and DVD's.
Good luck, you can't really go wrong so long as you start with something.

I have been using the kettlestacks since January and have found them to be very easy to assemble, use and it does almost everything a regular kettlebell does.
Since the plates are adjustable you can also set them lower than the cast KBs without hurting the forearms of beginner Kettlestackers.
I highly recommend them for their functionality. It's a great product.
I'm going to look into making base plates that can be attached to the main bolt so that renegade rows can also be done with them.

detailed reviews
Letting you know that the Kettlestacks (adjustable kettlebells) have arrived. My husband and i spent the weekend playing with them and we are very impressed to say the least. Excellent quality! We own a *** (adjustable kettlebell) handle (which my husband has never liked) and it dosen't even compare to the Kettlestack. The feel of the Kettlestack is supberb and we can honestly say that there was no noticible difference with our original kettlebell and the Kettlestack (except of course that the Kettlestack is adjustable and can easily be taken with us on our frequent travels), congratulations on a fine product!

Hi Guys at KettleStack,
Just received my pair of kettlestack. My first thought was: "they are so light they can not handle the plates!". I was proved wrong after my first kettlebell session with them. Solid as rock. Thanks so much for the attention and for this great product. Just made my day.

I didn't know about you guys before I bought a 35 for my first KB.
Presses were ok at first but they are getting too easy and swings were too easy from the start.
The forums suggested what my next kettlebell should be and some harder press moves, but I got off that train, purchased your product and can now focus on training instead of saving up for the next weight kettlebell. The kettlestack is a great product wish I knew about it sooner. PD

Pretty decent prices and shipping is reasonable as well, just thought I'd share with your guys here. I plan on getting the 7.5 plates from here if I can't find them local.
Hi Everyone !
Our updated product line still has a base, mid, and high option but things have changed!!! More kettlebell stuff . . .
I want to build up a 35 pound kettlestack
which slot should I use ?
Hi folks,
Just wondering what the best option is to get a pair of kettlestacks in Canada. Shipping them from the states? Or is there an official supplier in Canada that would be better?
i, thanks very much for the quick reply back to me. thats great news that you gave me. Sorry to continue with the questions but i have a couple more.
i only have Olympic plates (like the 10kg, 5kg, 2.5kg and 1.25kg) does your product fit olympic plates or is it just for weider plates with the smaller holes? More kettlebell stuff . . .
These things look like a great idea, but I've seen some posts about how they rattle,
That wouldn't be safe. What do you say about rattling ?
A customer sent us a picture of his 20lb setup (:

asking us if he set it up correctly .
That setup is pretty close to the "19" lber shown as part of this assembly sequence:
