Review on 🔦 SILK'N Sensepil Pro Disposable Lamp Cartridge 1500 - 3 Pack by Kaitlyn Nelson

I've successfully ordered replacement cartridges from Silkn but saw them on Amazon and thought I'd save some money. They came in the same packaging and I thought I had found a bargain. The first cartridge lasted about 5 pulses before my machine beeped and failed. I tried other packages and same problem! It doesn't realize it's run out of pulses, but it shuts down the machine before you can press the button to send the pulse. Maybe they are defective and shorting out the car? I'm not sure. I've tried both lower and highest settings and nothing changes. Now I will order new cartridges from Silkn.
