content: We're coming up on two years of steady use with this little jewel and very happy with it. It takes a little practice at first learning the proper way to position it, but I'm able to do it with one hand (No I'm not Hercules). My wife also gives it 5 stars and wants me to buy an extra one in case they discontinue it. She's not very strong and has never had any problem puncturing the can to get it started. It's very compact and comes apart easily to clean. This is one of our favorite kitchen tools. Highly recommend.
