GF4 Fryer - Would not recommend for commercial use at all! Despite it seeming flimsier that the usual free standing fryer it seemed to be ok, that was until it came to cleaning it! There is no room between the tank to reach the bottom, the hole that connects to the tunnel is ABOVE the bottom of the tank, therefore does not empty the remaining residue and oil! A cleaning rod comes with the fryer - which is essentially a long piece of metal, again you cant collect the residue as you cannot fit anything bar the rod in! I physically had to tip the fryer to completely empty it and at that i was still left with debris at the bottom! This was after 4/5 uses!!! Customer service was unhelpful and said because it has been used they wont refund, but i can email for advice?! I’ve worked with free standing fryers for over 34 years and never came across a fryer that you cannot fully clean! I’m now left with this until i can afford to buy a new one. I’m not someone to leave bad reviews on items but feel that businesses need to know this, as if i had seen a review about this i could have saved myself this hassle and purchased a fryer i can actually clean.
