First, the Web site is very good - providing a picture so I could be sure that it was what I wanted. Second, shipping was very fast. I ordered this as a spare for an old system, so I can't evaluate the item - but it looks identical.
I just need it for the heater to function.

Product worked as advertised. I wish it was made in USA not China.
Replacement for an out dated part
Made in USA would be nice. I am willing to pay more for US parts, if there is an option.

Original SensorTuesday, October 23, 2012
This is a vital part of a gas fired hot water baseboard heating system. Without it the furnace cannot start. The sensor detects the pilot flame in the furnace and when hot enough it opens the main gas valve to power the boiler.Thr saensors seem to deteriote after a few years-probably due to microscopic leaks in the pressure tube-which contains mercury. When a sensor fails in cold weather, the first job is to find a supplier who charges a reasonable price and delivers promptly. This was evidenced by DrillSpot who had a price about half that of local suppliers (typically $200)! DrillSpot's order was delivered fast and packaged properly thus ensuring that any repeat orders for this type of equipment will certainly go to them. Thank you DrillSpot for my warm workshop !!
Original manufacturer's item
Last longer than seven years
Recieved in nice condition.Thursday, October 20, 2011
The copper wire that is attached to the copper face of the 3098-149 switch on my Rheem furnace snapped right at the copper base. I couldn't re-solder, my iron did not get hot enough so took the switch apart, drilled a hole and inserted the copper tube and placed a bead of solder on the inside, it worked for one season. So my cheapness broke down and bought this new one 3098-156, which is a direct replacement. The thermocouple on this replacement is 10mm longer. I removed the "C" clip from the old one which was a pain in the butt (so small) and placed it in the appropriate spot on the new thermocouple (refer to the instructions). The difference between the spots on thermocouple to replace the "C" clip was either a little shorter or a little longer, there was no exact match. I chose a little longer and plug it in. The beautiful thing is that is pulls out and pushes in without having to take the ignition/pilot tube apart, took me longer to write this review than to do this whole job. I plugged the three prong plug into the gas valve and it fired right up. These thermal sensors should not be so expensive, the local parts store wanted $171 which is retail and I could buy a whole new Rheem 85% efficient furnace for $624 delivered (lol). Next year I may replace this 30 year old furnace myself of course.
Brand New, well built, copper wire was easy to unwound perfectly as to not create a mess or snap it off.
It could be cheaper
Exactly What I NeededThursday, February 03, 2011
It's hard to find parts for my 35 year old heater... and this was exactly what I needed. The local parts store said it would take 3 weeks to get and you got it to me overnight...thank you!

Product arrive in a timely manner, and was the item I needed. It resolved the problem I had with my furnace. However, product did not come with the needed small C clips. It came with several adapters, but each of these required C clips which were not included. The C clips on the bad part were not reusable due to corrosion cause from many hot/cold cycles. The part receives extreme heat from the Pilot light flame. There is little chance the C clips could ever be reusable.
Product was what I need, fit the application, and resolved my problem.
Instruction sheet could be much better, and the missing C clips mentioned above.
