Review on 🌱 Burp Lids Curing Kit - Perfect for Wide Mouth Mason Jars - An Essential for Home Harvesting. 4 Lids + Extraction Pump. Vacuum Sealed for Successful Curing. by Devin Lee

Operates the pump. Really nice job - the pump is cheap, plastic and small but I did some testing A:B: Pump and Kirby vacuum - Kirby didn't increase the vacuum so the pump here is reliable. -40 PSI Chamber - When using a vacuum pump and a chamber that can reach -40 PSI, the pump is the clear winner. But it's variable, meaning I could dial in the balance, and it was around -8psi, a very respectable number for that purpose. A few weeks ago I wanted to order another set but it wasn't available or didn't work. It was a unique and great product, I hope to see it again for these two reasons.
