I am on my second or third Rowenta in 25 years. I honestly have not had the issues many here have. When I was working in the corporate world, I ironed my clothes every morning with my Rowenta. After beginning to quilt, I still used my Rowenta. I either wore them out or dropped them one too many times. I'm a firm believer in that the type of water used is very important with Rowenta. Some are made to specifically use tap water and others specifically to use distilled water. Read the instructions and use what is recommended for that particular model. Also, check the wattage usage. Higher wattage - more heat/steam.
I forget what store I was in a number of years ago and there were probably 6-8 different Rowenta models on display at the time. Couldn't believe the variation in the wattage of the displayed models. Wasn't in the market for one at the time but curiosity got the better of me simply due to the number of different models displayed.
