I waited several weeks for this item to come back into stock, and paid a fair bit more (in percentage terms) than for competing products.
It's my first experience with an induction hob, and I'm not entirely happy.
I would've thought the "Precise" of the product's name had some bearing on its performance, but at the low temperature end there's just a choice of 80C and 120C. The 80C is OK for keeping things warm, but 120C is too hot for gentle frying. I wanted this hob for jam and marmalade making, and using with a pressure cooker, and do not think it will be suitable. The Judge induction hob has 20C steps, starting at 60C, which I think it achieves by cycling the power on and off. This would have to be done manually with the Salter and I'm already convinced it's no good at frying onions the way I like them, and can achieve with ease on my conventional hotplate cooker.
I'll test the temperature settings with a pan of oil, but with water the 80C setting is accurate to about +/- 4C (depending on whether the lid is on the pan).
The timer beeps somewhat annoyingly when being set, yet only emits a single beep when it's completed its countdown and switches off the heat.
Pans need to have a base diameter between 12 and 24cm, so there's not the convenience of slumming it and heating soup or beans in their can.
There's little explanation of the program functions e.g. for soup it says 200W for the first two minutes, yet 400W (for 80C) is the lowest setting possible. The hob actually starts off at 800W with the soup program, so I assume that's for frying (burning!) the onions and you'd need to have your liquid ready to add at the end of the two minutes, when it whacks up the power.
In conclusion, I think this hob is best suited to boiling, steaming and high temperature frying, and could be useful for reheating and keeping food warm away from the kitchen. The Judge hob is cheaper and also has a two year warranty, while seemingly offering far greater control from 60 to 120C.
Update: Testing with a pan of oil, the temperature just rose ever higher. The temperature settings had little relevance when cooking and maintaining the bottling temperature of a large pan of chutney. After about three weeks, the hob has failed with an E5 error code. It seems to be yet another example of a UK-badged Chinese product, with poor engineering design and quality control, and the buying public being used as testers.
