Curing units, is there a universal curing unit? one that cures all gels? Should you buy a curing unit for every brand you own?

So this topic of curing units is slightly controversial. The experts say Yes, you need to use the lamp that is sold by the brand of products you use. The nail tech on the other hand is like well I use a number of brands, and the DIYER says I use a ton of different brands and I also don’t want to spend over $50 on one…

So what do you do?

First and foremost... please, please, please narrow the amount of brands you use. YOU HAVE TO. This will not only save you money but also headaches trying to troubleshoot what went wrong in your application with all the different variables of mixing brands.
