First, and most importantly, you will need to measure your wheels rim depth and then order the appropriate sized valves which are needed to make this product work. Those valves are ~$40 a set. If you have different sized rims front to back, you would need two sets of valves. Also, quite a few sizes of valves are out of stock, so check first.
Second, even with the correct sized valves, it's hard to get these valves to seal. They say that the top nut only needs to be finger tight, but despite double checking everything, mine needed to be screwed down with pliers to make them seal,otherwise air just leaks from the bottom of them. That means, you need to carry a small set of pliers on your rides if you ever need to remove them to install an inner tube! If you remove a tire, it seems that it loses its seal and you need to play around with the top nut again to find the perfect point that it does not leak.
Third, if you get past the first two items, these only connect to your Gammin headunit via the Tyrewiz connect IQ app. That's fine, but I have found that if I am riding with other riders who are also using Tyrewiz sensors, we get cross talk where I pick up their tire readings on my headunit and vice versa. The only fix is to get your bike out of BT range of their bike and reboot your Garmin. Thankfully Garmin can do that without losing your current ride stats.
Fourth, when everything is working, it's absolutely great. Riding with your tire pressures showing is incredibly reassuring, especially on fast descents. Knowing you are not imagining a puncture could save a crash. For all the negatives posted above which I now khow to resolve, I love them. Just be warned though - they are not plug and play.

These are awesome, great to be able to monitor my pressure while riding. Sometimes it has trouble connecting to my Garmin, not sure if I need to update my software.

Sure beats having to pull out a gage to check pressure before and doing a trail ride. A bit tricky to install if you are using tire inserts but all you have to do is cut out some material in the Cushcore so that air can get to the TyreWiz.
