Sistema Breakfast Bowl

3RD UPDATE: Ended up throwing this piece of junk away b/c of how frustrated I got every time using this bowl. Never will buy another Sistema product ever again. Overflows every single time using 40 grams of regular oats. Just read the description on the product page. "Simply heat the contents in the microwave and then eat straight from the bowl. This microwave bowl features a lid with a steam release vent for SPLATTER-FREE heating and cool-to-the-touch, easy-lift tabs." Nope. 40 grams of regular oats, overflows every time before even being completely cooked through. Not simple or splatter free at all.2ND UPDATE: Look at the pic. Still overflows if you put room temperature water and anything above 40 (1/2 cup) grams of oats. I put 60 grams of oats as I am upping my total caloric intake and it just overflows out of the steam opening. No better than a glass bowl and not worth the money you pay for this piece of junk!Update: At first, I used 40 grams of oats and put in hot water from the water cooler. It overflowed within 30 seconds of cooking through the steam vent and I had to pull the steam vent off to clean the bits of oatmeal. Frustrated after cleaning up the oatmeal, I wrote the review below.I have since used regular room temperature water to cook my quick cook oats at 1 minute 30 seconds to 2 minutes and it does not overflow in my 1200 watt microwave. The bowl is cool to touch and is much more comfortable in cleaning the bowl after eating as the oats do not stick to the bowl after drying.I knocked a star off b/c it is not leak proof and nowhere in the instructions does it say to use room temperature water. Some people only have access to a water cooler at work and most people will not be putting in cold water to there oats, they will put the hot water side and then stick it in the microwave to cook it a bit more and faster. If you do this, you will be cleaning oatmeal off the sides of the bowl and microwave. Make sure to use cold or room temperature water. Also the vent lid does come off, you just need to pull on it a bit. Not sure how durable the tab feels as it seems it could break if you pull off the tab too much.All in all, I am now satisfied with the product, but it seems a bit expensive for what you get so I knocked another star off for the value. If it was leak proof it'd be worth the money.Previous Review: I purchased this thinking it would prevent overflow of the oatmeal since you know you designed it to cook oatmeal as the description right on the bowl says. Nope. First time using it, the oatmeal overflowed through the steam vent. Instructions state to open steam vent before microwaving. No better than your average bowl. Also a lot smaller then I envisioned. A waste of $7.29.
