Considering the quality of this pressure cooker, I do not have any certain information. But I guess it's not a durable product, since you are able to find a Phillie Richard pressure cooker for the price of $29.99 only. But in case this slow cooker is not able to deliver what you need, you can still use it for different purposes. Sometimes it happens that a new cooker can't keep the pressure, but you can still use it as a regular pot, making soup in it and other meals. It's great that they are so thick so they are very useful cookware in overall.
Once again, if you have those 30 bucks, try to purchase Phillipe Richard cooker and see what you can get out of it. If you want something more serious, then a Fagor, Presto or Nesco cookers should be your target.
