I have done the following;
Posh Floors

Tile Doctor

MarbleLife

At Posh Floors, I stood all day polishing a 2sqm floor. Would I recommend it? NO! Waste of time and money. Whatever you do, do not buy their machines, I did... and found out that their customer service is disgraceful.

Tile Doctor. Would I recommend...No!

Why?
Polishing marble is encouraged with Twister pads, nothing wrong with that, they do work but, polishing is best done with diamonds, as taught by Kevin Martins course.
Having used Tile Doctor products, I have thrown them all away. Make up your own mind on that one!
If you decide to join the Tile Doctor team, they want £100 a month to add you to their website...£100 A MONTH!!
Thats not all....The paperwork that you fill in at a customers house costs you another few hundred quid....in my opinion A RIP OFF!
Oh and just one other thing....NEVER speak to others on any forums about them, they don't like it.

Other than that, they do buy you lunch on their course, which is nice.

Kevin not only runs a good course, they also have decent kit to use. Klindex probably make one of the best machines on the market, The Levighetor.
The Levighetor will be added to my kit as soon as I can afford it.
They are always happy to answer questions over the phone and offer advice. How much is that worth?
AND....their products work.
Not done Nu-Life, maybe I will in the future.
Hope this helps
