Perspex hob Lid

Like one of the Posts above the Igniction on this cooker would not ignite after quite a short time ..and hvae remained so until this day ... but .... but worse was to follow ..
The Perspex Hob Lid shattered in tousands of pieces in November
spraying pieces all over the Kitchen - it was not chipped cooker was not on , the oven had been on about 1/2 hr earlier
I have been intouch with Indesit who are the resposible company for advice etc ... in December I asked if they could give me a gaurantee that if I bought a new Hob lid that it would not shatter again
Following a prompt from myself last week I was given no such assurance
they can not gaurantee .....

This is most unhelpful to myself as I can't decide whether to spend good money on replacing the lid or not , I found it most useful as a splash back really

Anyone else have a problem with the Persplex lid
I also intend to inform Health & safety executive of this incident , we were fortunate that we weren't hurt but could so easily have been badly hurt or have got an eye injury
I say watch !!!
