I bough this for my family during the summer as we wanted to have a BBQ but didn't have a proper one. They were reasonably priced, very portable and best of all - it worked! I have purchased similar versions of these BBq's in the past and have found that they havn't produced much heat but this one produced plenty enough to cook our sausages, burgers and kebabs. The bbq sustained it's heat for just under an hour which was plenty enough time to cook for 4. If there had been more of us, ie 6+, we may have struggled to cook everything on time. But a simple solution would be to puchase another unit. After we had finished it was a simple case of leaving the unit to cool over night and dispose of it in the general waste the next morning. Overall it was a great experience (i've brought a stash) and I highly recomend it!
