There are lots of great lamps and gels out there. But if you are interested in OPI you should be forewarned that it has been difficult to cure in some lamps.
Did your friend recommend the CND LED lamp? I actually got one from someone who wanted to get rid of it. I used it for my current mani (I used all CND products). The mani came out great. As I said above, I really like the shine and durability of the Xpress5 topcoat so far.
I haven't heard anything about how well the CND LED lamp works with Gelcolor or any other brands. This lamp was "supposedly" specifically designed to cure the older CFL-UV Shellac as well as their newer LED formulas. In their advertising they made it seem as if the lamp technology might not be generalizable to other brands. I know that it is probably all the typical CND marketing hype but still I worry that it might not work properly. I have only used the new CND LED lamp with CND Shellac and Brisa Lite. Since I have the great OPI LED lamp I haven't wanted to bother experimenting with other brands in the CND LED lamp. Did your friend have any information on this?
The CND LED lamp also has a 60 second cure time instead of 30 seconds, so it will be a little slower than the OPI lamp (or the Gelish 18g) .
BTW here is the link to the thread I mentioned earlier. I know it is old but it has lots of great info.
