First time I've seen this type of product ---
I've never had a tire valve stem break, nor been on a trip where that happened to someone else.
This product might be something you put in your "Spares" box and never need.
But it is interesting, relatively inexpensive, and would sure come in handy in the right situation.

Interesting, I think you may have never seen a valve stem break is because most tire shop replace the valve stem when you get new tires. At least the
places I buy tries do.

My Tacoma wheels have metal valve stems and they have the TPMS transmitters on them ($60 to replace when the battery dies after ~10 years). TPMS
alerts your dashboard if a tire has lost significant air pressure... ie. going flat. Great warning as it has given me time to find a safe place to
pull over and plug the hole before going totally flat.

Got those sensors also
It would seem that the sensor that is mounted somehow to the valve stem inside the wheel would come loose when you forced the broken portion of the
valve stem back inside the tire.
The video I watched on the website doesn't address the TPMS equipped vehicles.
I emailed them to inquire about TPMS wheels. I'll post their reply.

Thanks John! I am guessing this is for rubber stem, tubeless tires only? A neat idea, but all new vehicles have TPMS, at least the last 10 years now.

Valve stems break? That's possible but not probable. Driving 50 years and never saw or heard of one breaking. Total BS.
I use a TPMS on my RV. Shows the temp and air pressure of 6 tires on a portable monitor. Saves manually checking the tires every morning while
on the road. I like the peace of mind.
New metal stems on my truck and RVs, rubber on the cars. No cause for alarm.

What I have had happen and seen happen to others is the schrader valve itself coming loose and air escaping the right out of the valve, this is what I
carry in my kit to tighten them back up
also comes in handy to air down quickly for some beach driving

My experience has been rubber valve stems will deteriorate over time.....before they "break", unless they are torn by debris, etc....Keep an eye on
them....tire shops won't always....
Don't believe everything you think....

I have broken metal valve stems at least twice while rockcrawling. I've seen broken stems on friends' 4x4s. I used to think that metal stems were
stronger and the way to go. Now I run rubber stems. "FLexible" is a type of strength. Rubber stems bend like a palm tree in a hurricane, while a metal
stem will snap off.
John M - thanks for posting up. Great device! A little too pricey for a spare part in my kit. An elegant solution though. It appears to fasten just
like a concrete "wedge anchor".
While rockcrawling in Big Bear, I made a temporary trail fix by refilling the tire with air, then forcing a plug into the hole of the broken stem
(easier than changing the tire in the boulder filled stream bed).

There was a time when valve stems were a major issue the result was people who had them had to get replacements.
I think it was the metal stem that used a vulcanized rubber at the rim
Anyway I had them on a trailer and had to replace them along the way. The tire guy used the same ones and they failed again. Fortunately they fail
with a slow leak. As soon as I got to San Felipe I had the tire guy replace them all with the plain rubber ones.
For off road use and no TPMS we avoid metal stems because they get broken off by sticks and rocks. Best choice is stubby rubber ones with little
metal for the stem. As noted a very flexy stem is what you want.

''Your tire valves are probably your vehicle's weakest link. One hard impact and you're in a world of hurt. Don't take the risk. Be prepared with the
best valves available: Colby Valves.''
Yeah it's your vehicle's weakest link if you're rock crawling. For the rest of us, valve stems do not break. Colby website is marketing this
product as something the general public needs -- because their stem can break.
Not really.

Seen lots of broken valve stems with my rock crawling friends. Metal are the worst. Not really a problem on mild 4 wheeling.Also had a horse tied to a
trailer and he busted one off. That was a real rodeo.

Now days many aftermarket wheels come with a recessed valve stem. The thing sticks out just enough to make to be functional and when used with the
rubber ones with very little metal extension then all is well.
People with late model TPMS Ignore this discussion or disable it or get proper wheels for offroad use.

Follow up with Colby
I contacted Colby via email and asked about use of these in the event your wheel has a tpms attached to the inside of the valve stem.
The answer was yes, it will work. In forcing the broken piece of the valve stem inside of the tire/wheel, the tpms sensor will also drop inside of the
wheel.
Remember this is considered an emergency fix - and Colby said that these are re-usable.
While the tpms that bounced around inside of a tire for fifty miles probably not reusable.
I suppose if you had the proper tools and spare valve stem you could fix it the old-fashioned way.

I have had a valve stem fail on a trailer, likely just age. Looks like a good addition to the spare parts box. Thanks for the heads up!
