This item arrived earlier than expected and was securely packaged.
In common with other reviews, the fact that the fixing brackets do not hold the heater securely did present a small problem because of the way in which I deployed the heater. It was mounted on a piece of 6 x 1 timber so that it could be moved from area to area as required. The loose fittings were overcome by fixing two metal brackets, one at each end, to stop the tube from moving laterally.
The heater is at presently in the washing area of the garage providing heat to prevent pipes from freezing, they have already had one split in the present cold spell and the heather serves to prevent another.
Because the garage is a large area to heat, double garage with roller doors at either end, it is noticeable that the heat from the tube is very localised and it does not present a hazard when located between the wall and the washing machine. I had considered buying a thermostat but decided it was superfluous under the circumstances.
The bottom line is that it is a good product that is working in a less than ideal environment.
