I prefer TST's standard 507 sensors. With the security covers removed, taking one off to adjust tire pressure is no different than removing an ordinary valve cap. Removing the security covers also makes them smaller and less noticeable.

X2. I also recommend you go to steel valve stems if you have not already. Love my 507. I replace the batteries about every 2 years. They can be found on Amazon for about $7 for a pack of 10.

Have had both the regular and flow through sensors. They are a bit slower to add air with my current flow through sensors. No big deal, though. One of my sensors is actually very slow to add air compared to the others. Haven't called for a replacement, but after my previous excellent customer service from them I have no doubt they will be taking care of me as always.

Debbie is who I spoke with in the past, and she is, indeed, very good at her job.

we have the original, non-flow 507s & work fine.
under three seconds to remove the sensor and then add air.

You'll be impressed, speaking on the phone with people at the firm ("Debbie", who will sell you just two if that's all that is needed) and received a nice return e-mail from the CEO (after complimenting how Debbie and the installation/programming videos are incredibly helpful).

Have the flow thru no proplem adding air.

I bought the flow through, but wish I had bought the non-flow through. The air is SO restricted going through that unless you are only adding a pound or two, you still have to remove them. If you only need to add a pound or two, you don't need to add air anyway. They stick out much farther is the drawback.

It IS nice, however, to be able to put an air gauge on it.

I have the standard sensors and have 4 on my 5'er and 4 on my TV. When I get to a site for an extended period of time I remove the 5'er sensors to preserve the battery life and put them back on when ready to move. The sensors on my truck I never remove. I verified the accuracy of the sensors with a tire gauge initially and as long as the remote in on my dash doesn't change, I never check them again except at battery change time. I do check the pressure in the 5'er tires when getting ready to move, but unless the sensors are removed for some other reason I don't check the pressure with an air gauge.

when all else fails use the KISS princeable use str. 1's no need for freed thru i have sta & took off security things

X2.

Bought the first set of regular 507s in 2011 and used them on our TT. Then when we got the MH bought additional sensors to use on it and the tow'd. Occasionally the signal from a rearmost sensor would get lost, but that was resolved by getting a repeater.

I'm running the flow-through sensors on my trailer. Have had them a couple years, very happy, don't feel there is too much restriction. I have just purchased the internal sensors for my truck.

Talking to TST, I was advised / encouraged to get a repeater, as the internal sensors can have a tough time getting the signal out of the wheel?!?!? That wasn't something I wasn't expecting to hear as OEM sensors don't seem to have trouble. Time will tell, I'll get them mounted up July 11th.
