I received the Aully Park Digital Gauge (with accessory kit) this week. Pros: It was easy to assemble and easy to attach to my compressor hose. The ergonomics are good, at least for my hand size. June 6th 2017 Pro Update: Customer service is AWESOME (more below) Cons: This is the main downside, the shutoff end (the end that attaches to the valve stem) is constantly leaking air. It appears to be leaking through the gasket or straight into the silver locking mechanism. The leakage is significant - if it is not attached to the valve stem, there will be a loud noise from the inflow of escaping air. With it attached to the valve stem I can pump air into the tire but the pressure gauge is low due to a leak. Customer service is AMAZING (updated this comment on June 6, 2017): After I posted CON in my original review, the seller contacted me immediately and offered a full refund as they pride themselves on having a good quality item . Since the product didn't work, I wanted a refund. The money was fully refunded within 24 hours. Very impressive customer service! For this reason I have raised my rating from 2 to 3 stars. I will give the supplier/manufacturer the opportunity to remedy the defect. Failure to do so will result in the idea being returned as a defective product.
