DKN has been around for nearly 18 years. Their machines have very high G force capabilities, reaching 12 G forces on some. Their amplitudes reach 3.9 mm. This is a new line I am considering to carry. If anyone is interested in being one of my first few customers and can give me feedback or possibly make some videos with your machine, I will help.
We just finished testing the Xg10 DKN model. I absolutely love the Xg10 model. I am now selling all of the DKN models.
So far I have not had one return or any complaints. So far I have only tried the Xg10 model. I will be trying the other models of theirs shortly. If you are interested in a DKN model please call me.
Update:
I just finished trying out every one of their models. I have to say I am very impressed with all of their models. Their Xg10 model is very powerful and I can see why it is in most gyms. I was at a fitness store and held 75 pound dumb bells and their Xg10 model didn't even know the difference. Their other models are good for lighter users but I think the Xg10 just might be in my top 3 favorites for linear machines, with Hypergravity Gyminator and Powervibe Zen Pro, my other two.
