Review on 💡 Silk’n Flash&Go Replacement Cartridge: 3-Pack for Long-Lasting Hair Removal by Sara Hunter

I love Silkin Flash and Go. My dermatologist actually recommended it, his wife has been using it for years. I brought it to him, he showed me how to use it, I had almost no facial hair. I ordered 3 pcs. Replacement cartridge, one does not work. I am currently using the latter. I wrote and informed Revine that a cartridge had failed. I never received an answer. I'm wondering if I should order 3 packs again or choose a longer life cartridge? I've been using my newest since today. good product. I love it.
