Not good

I've been preparing my nails really well, indeed I did not use primer because I do my own nails only and using the gum base I never needed it. The gum base really worked great. But this one is not strong at all, my nails keep bending so badly, they always break with this base and the coats are completely coming off. I always "seal" my nails and do them properly, this base is just horrible. I used non name basis without primer and never had an issue. I will now order a primer and hope that this will not happen again. I will come back with a review after that. But without a primer, don't even think about getting this. Worst nail product I've ever tried from any brand (and I tried many).
