AEM's Bosch 4.2LSU Wideband UEGO O2 replacement sensor kit includes only the sensor (with attached cable and male connector) and is intended to replace an existing mounted wideband sensor used with AEM wideband air/fuel UEGO controllers. These sensors have a laser-etched, calibrated resistor in the sensor’s connector body. This resistor is specifically created for the exact sensor that it is attached to. Modifying this will invalidate the sensor’s output.

Slow support
Color: Green, Size: 15"x15" 8 in 1
Seems to work ok. It is lighter than expected which is a plus. Support is very slow from company and did not come with instructions. You have to email them for a pdf copy.

Very clean look to it. Heats great. Very sturdy design. Heats evenly and does great for vinyls, sublimation and dtf. The instructions were clear and easy to read.

Temp Sucks
Color: Black, Size: 12"x15" 5 in 1, Color: Black, Size: 12"x15" 5 in 1
I got the 8in 1 inset wad of the 5 in 1 that I had originally ordered. The seller contacted me about because it was the holidays they decided to send me the 8 in 1. I never had any trouble with the mug press before. My temp was 365 for 60 seconds and the burning never happened before. Then I put my cup in and my press started to smoke. The sublimation paper started turning brown and smelling bad. So I turned the temp and time down to 345 for 30 seconds. But when it was time to press it, the temperature went over 500 and started rising. So I turned it off and turned it back on but it did the same thing. I don’t know what to do. I can’t get a refund or even return it. This mug press sucks. Don’t waste your time!!! %%Update%% I can’t do this anymore. This was the replacement they sent me and it already burned my tumbler. I only used 330 for for 30 seconds and after the first turn the paper was brown. Then it started smoking. I can’t keep wasting tumblers on the mug press. My room smells like smoke. This never happened before. I used 6 tumblers in this machine before it started smoking. I’m going to buy another tumbler press. Not from here. &&Update&& They sent me an entirely new machine with attachments. I think the problem was the control box but now I have doubles of everything
