I really love pressure cooking but I can’t recommend this Power Pressure Cooker XL (ours is 10quart) brand. The first 8-10 times I used it, it was with wonderful food results. HOWEVER, it’s a challenge to clean crevices properly without unscrewing bottom. Teflon stains and wears down immediately. I enjoy the extra components that come with it but you have to stack it properly inside to store and it’s super HEAVY. Also, after about 10 uses, we could not get the unit to PRESSURIZE seal. We bought 2 more Rubber sealing rings since ours seem very loose after about 10 uses. ALSO, Pressure seal/valve Vent about never seem to hold in position in OPEN or CLOSE...just keeps spinning. I’m really wondering if we got a faulty unit.
