You should know that others appreciate the product (Kettlestack adjustable kettlebells) for reasons other than saving on shipping costs. Hope this can serve as some positive feedback for what you have done. It's appreciated on many levels - as a real design triumph, backed up by wonderful service, and most importantly...a functional piece of training equipment. PN, Fargo ,North Dakota
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?

Kettlestacks are solid as rocks.
that guy from brazil

had it right.
I've seen some posts from the sock puppets on other forums;
They're either lying or clueless about bolting things together.
Thanks for a great product!

My pair of kettlestacks has served me fine for several months now on my "fitness path",I'm fitter than I've ever been!
You guys have been helpful every time I asked a question. Now, I see these other forums where people put the Kettlestack down, and I don't understand what's going on. Who are these people ?
Just got my first Kettlestack (adjustable kettlebell). I love it. Feels just like regular kettlebells. The cost is equal to the shipping cost of some kettlebells! SL, Brooklyn, New York
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!

I've been using my (Kettlestack adjustable kettlebells) handles about 2 months, and I couldn't be happier with them. Your product: is rock solid, easy to use, ingenious and cost effective...I had planned to buy a solid "KB" next paycheck, but I want another "KS" first. GL, Los Angeles,California
I've got the old style Kettlestack, which I enjoy immensely. I arbitrarily chose the middle hole for all my Kettlestack builds (35 to 55 pounds). Do you have guidelines for which hole to use (e.g., for less than 25 pounds use the hole closest to the handle)?
I tried a couple of brands of cast kettlebells today. I found that they caused intense pain in my wrist--they hit a spot much closer to my wrist than my Kettlestack. I'm wondering if they have a crappy design, or am I spoiled from my Kettlestack!
I would like to purchase another kettlestack for double KB movements--can I set up a new-style Kettlestack such that it has the same height as my old one?
Thanks!
I got my next kettlestack handle. This time it's the new model that
the front page shows.
It's a little wider and a little taller. The bands are finished in a
black instead of the blued steel on my first handle.
It didn't seem that new or different until I built up my 57 then I
noticed some things.
It was easier to set up a round shape close to the 45 on the front
page. Now it is really close to a solid KB.
On presses, the stack sits higher on the forearm. After I felt this
difference I went back and pulled the old handle out farther from the
stack and it felt better. It just happens more naturally with the new
design.
And on two handed swings there's a lot more room for the fingers.
I know you kettlestack guys know all this but small improvements add
up and you've got a better product. I'd say much better except that
makes it sound like the old design had problems , and these are fine points that just made a great product near perfect.
Thanks,
TZ
I'm very impressed with the quality of the Kettlestack and truly impressed with the speed of the shipping. Great job and I appreciate the followup email. It's only January and you already earned the 2005 Company of the Year Award. IR, Juneau, Alaska
I'm trying to figure out which hole I in the handle bands I should be using? There are 3 - a little one (same size as the Allen wrench) then 2 big ones. Do I use the top big one or the bottom one?? Seems to make a lot of difference as to where the weight lands on my forearm.
Thanks,
PS. Awesome product.
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?
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
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 ?

Here are some updated hardware pictures of the new (now over a year old) kettlestack design; 1/2"x13 hardened Grade 8 hardware and rockwell 52 hardened steel support straps:

(mid hardware shown has some extra bolts)
More kettlebell stuff . . .
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 . . .

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.
