do you need two or just one?

You will need only one. I thought the of the same question before I bought mine. I have bought two, though. I have one at home and one in Afghanistan.

I believe you only need one, the way this works is by isolating certain muscles during workouts, so ideally one is all you need, it comes with a little panflet manual and a dvd that shows the exercises that are done using a single shake weight.

I only need one. It's another piece of 'variety' equipment I use from time to time. Hadn't any thought given for using 'two' yet as I write this I can see there are possibilities, such as doing 'shakes' at the same time using both arms separately. You know you got me thinking now, ha! Always be open minded when about training. Always some new & good ideas out there. And I've been training over 50+ years. You might be on to something, that is using two. Mike

only one. you should buy two so they work together, otherwise the weaker one will wear out the stronger one faster.

I agree with everyone here. You only need one. It worked perfectly for my car and appears to be much stronger, it handles much more abuse.

You do not need 2 people. Many people only use 1. Why do you think 2 people are required?

I only needed one for my bike, couldn't say with your. I should think you'd only need one as well, can't think of any reason for more. You might check your bike--see if there is not than one, and go from there.

just one, in my case I use a "T" and use for two thanks because its very strong, before that we used both from other brands.

No, one is sufficient. See Michael Walls answer for a good reason to have two shell holders. I also use two for the same reason

It is just one, but that should be all you need, unless your setup is very unusual.

Yes you'd need two...beating up the dummy gets a little old after awhile :-)

Correction. I believe two but only use one. Suggest you contact the seller directly.

Yes, you need at least 6, but can add another 2. The instructions explain it.

Honestly I don't remember if you get two but all you need is one at the Tip....

I'm reading that there is only ONE per order. So if you need two, ya gotta order a second unit.

No, you do not need to use two if you are using both hands. Using 1 will ground your entire body, eliminating any static. At that point, you could use both hands and both feet if you wanted!

It's only one since you dont need more than one. The material is excellent, you won't regret.

one. you can order 2 with extra s & h. i can only use it when everything is quite. it is a sound amplifier, so all sounds are to much noise. hope this helps
