This is our third Hailo product in 18 years.  We went through two of the previous model and used it constantly in the kitchen.  The previous model had a weakness in that the rails were not as sturdy to repeated open-close and sometimes accidental side force application.  Each of the two previous products failed at the rails.  This one has a different rail that looks like it would be more resistant to the constant use and abuse.  The frontal grip is also improved.  I’m happy with this product.  I’m hoping it will last 10 years or more.
