Elica 773 CT Vetro Ai Burners were not so easy to use and it was really a complex thing to know about.the quality is really poor and need to take service for every 2months and for cleaning purpose we should be very careful and it was not so easy.considering the brand I found a mistake like this was not really upto the mark and durability is matters and it was heavy to carry to.this was not really best in design and style as we know that it will be in kitchen itself, but this should be designed in well manner and should be so unfriendly.it was not really upto the mark and fed up of using this one. truly disappointed.
