The problem with try me kits is that there are many potential problems one can have using them.
For instance, if you prep the same as you do with another system (especially one you are upset with because you have lifting) than you may very well have the same problems you are having now.
If you use a brush you have been using with another system, you may have discolouation problems or other forms of service breakdown.
If you are unsure of the mix ratio and workability... more problems.
Therefore, I am not usually overly fond of try me kits though saying that, I still recognise their importance in investment into a new system.
Now I have gotten my personal feelings on try me kits out... Ill try to answer a couple of your questions :wink2:
Yes, CND do try me kits and they are availible in the UK for qualified nail techs. In fact, if you are going to GMEX... I have a very limited number of a very new system that you can try out as long as I have enough at the stand *winkwink*
As far as coversion courses, they are currently only the price of the kit (which is close to 50% off anyway) and the course if FOC. That is availible for qualified techs. Your best bet is to call Designer Nails and speak to an academy advisor.
Hope this helps
