I am really impressed with the design.Far and away the best adjustable (kettlebell) handle on the market. Thanks for a great product. JT, Iowa
Hey these are cool toys for working out with.
The videos are pretty good, but this forum could use some work.
Thanks,

You have a great product and I would like to order my second handle. Please let me know when you have the high option in stock again. Thank you. JV, Georgia
The delivery ((Kettlestack adjustable kettlebells)) was quick and the assembly was even easier than I had expected. Also, despite my worries about how well it will work with Olympic plates, it has been very OK. Thanks once again and best regards, OU, Finland
I am not very verbose,so all I can say it is a great product. Back home in Berlin I used to have a Russian friend with kettlebells (24 kg and 32kg), so I can compare. Your product is for me as good to use as the real kettlebells, and has the obvious advantages of being much easier to transport and adjust in weight. MS Germany
Hi kettleguys,
Just got my kettlestack handles - they're great.
At first i'm wondering how strong they'd be, but once the weights are clamped in it's together!
and I savd a bunch on shipping- I'd be wiped out if I had to pay for shipping a pile of kettlebells to PR.
That tip about swings with a single heavy kettlebell worked great also.
You guys have a great product and great service.

Everything was great and he loves them! I appreciate you getting the information for me on where to get the weights--the guys at Play it Again Sports were very helpful. (JG,Missouri
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.

These things are great. I have 3 here is my payment for 2 more!
It is really a genius idea that solves a lot of problems. I have more than one set as as luxury to allow me to move quicker between sets. When these arrive I'll have 2 as 35 lbs, 2 at 55 and 1 at 70. As I get stronger I'll go to 2 55s, 2 70s and 1 80 or 85. I priced out some fixed weight KBs and price-wise it made no sense. I have been working w/ your product for a few mos and I am very pleased.

Please view our assembly video More kettlebell stuff . . .
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:

Hello,
I recieved the kettlestack this afternoon...I love this thing...I'm having trouble thinking of functional differences between an actual kettlebell and it...real well made product...
I had a quick question regarding storage though...should I loosen the bolts or even undo the whole setup every night for longevity (of the kettlestack) purposes?
Thank You
RJ
Hi Everyone !
Our updated product line still has a base, mid, and high option but things have changed!!! More kettlebell stuff . . .
The first step to getting the best kettlebell shape from your Kettlestack is understand where your forearm is going to land.
For most people that will be around 2 o'clock according to the clock we've superimposed over the image of the kettlestack.
Take alook at how the plates are tapered on this pair of 35 lbers. More kettlebell stuff . . .

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.
