Roger,

Generally instructions that come with the devices will prescribe using heat conducting paste. It will provide a good 'connection' between the sensor and the source of heat.

Regards

This eBay seller is having a laugh.  I really don't know what planet he's on.  First he listed it at 2.99.  Then he raised it to 3.99 and now a ridiculous 9.99. 


Showing as 2.39 for me.

Almost certainly he is using an automated pricing tool, as demand spike the price gets adjusted automatically.

Contacted the seller. Apparently his staff altered the wrong items. Got five at a good price !
