is that a special bundle? i didnt see that when i was ordering, have you factored in the VAT as i got hit for that on delivery (seems most do) and then a royaal mail handing charge which was near double that again. £6 VAT and £8 RM charge after i just checked.
after using it a handful of times I have to say i'm not 100% convinced i needed it, and its not fool proof, during this weekends cook with a temp of 230c set it actually dropped to 201 when it was raining a little. i know this will test its capabilities but it never managed to pump in enough air to get it back up, i had to shut it off, and open all the vents to allow it to work, I was restricting the airflow with the lever ball about 50% probably so clearly hamperig its abiity but no more than you will be with the spee controller.
