Is there a big difference between derminator 2 and ultima a7 ?

Like in the title, did someone have both of those products and can share their expierence? I would be grateful.

Just buy the derminator, no reason to be cheap on that, you can use this device for years.

In fact, the creator of the derminator promised 10k$ to the person who finds a better cheaper product.
