For my purposes, I give this product a vote of high confidence. This gauge is supposedly calibrated to industry standards, so I trust it more than the readings given by the floor pumps and the TPM. Using the TPM (tire pressure monitor) on my 2018 Subaru Crosstrek (which reads all 4 wheels independently), I found the TPM reads 2psi lower on all 4 wheels when the tires are Inflated to 35psi using the gauge. JACO Superior Products JACO BikePro Presta Tire Pressure Gauge 60 PSI - with Interchangeable Schrader Valve Air Chuck - for Mountain Bikes & Autos 2.4 out of 5 stars3 ratings 58.1458. Inflating my bike tires to 100psi using two different floor pumps with built-in gauges ( a Bontrager and a Topeak Joeblow), I found one pump consistently low by 4psi, the other consistently high by 1-2psi. Lacking lab grade instrumentation, I can't vouch for absolute accuracy. Both chucks allow a quick measure of air pressure WITHOUT lots of air escaping when attaching or removing the chuck. No tools are needed to swap chucks just twist the threaded chuck with your fingers. All said along with its rugged looks and seeming robust build quality, it should provide a long useful life, or so I hope.Ī product that really does what it's supposed to do reliably! I've used the Shrader chuck to check my car tires, and the Presta chuck for my road bike. As far as accuracy's concerned, it's at least as accurate as other gauges I own if not more so. Similar to other air pressure gauges on the market today, it has a very useful pressure release button that at least for me, allows for a more accurate and less rushed reading of the gauge.

Also, the Schrader air chuck when used in combo with the air hose that's attached made checking tire pressure on my vehicles easier and far less fussy as compared to all my other pressure gauges. The pressure gauge in addition to arriving in a well packaged shipment turned out to be a genuine pleasure to use which is mainly for its Presta air valve compatibility (for my bicycles' wheels with Presta valves). Overall a great sensor, but a carrying case would make it near perfect.Having purchased and received this a couple of weeks before even opening the package, it dawned on yours truly it might be a good idea to check it out before its 30 day return window closed no worries as it turned out. I haven't tested accuracy with several other sensors, but I tend to think this one is the most accurate. Once I figured out where to insert the silicone tubing, everything worked great. It would be nice to at least be able to attach it to the hose or better yet provide a carrying case with space for the nozzle when not in use - a spare silicone hose would be nice now that I know it's the gasket that the Presta is rubbing against -Threads and can wear out over time. If I keep it in a safe place, it will never be with me. Thing is bulky and heavy - A place to store a spare nozzle. Nice to have: - A carry case would be ideal.

Again, what am I supposed to do with this silicone hose? Through blind luck and trial and error, I finally found out it was the stem seal. Has the liner in the shredder mounting tube become loose? Without a diagram or instructions it makes no sense what it is and what to do with it - there are no instructions or assembly diagrams. A few questions: - The Presta does not have a silicone liner installed. Schwalbe Hans Dampf Tire 27.5 x 2.35, Tubeless, Folding, Performance, Addix. For the assembly of tubeless tires a large air blast is required. I like that it keeps the readings until you decide to delete them. The Schwalbe Tire Booster is an addition to your regular floor pump. I like the priming feature that lets you set the pressure. Solid brass nozzles and fittings, real rubber hose, beautiful dial.
