Review on 🚴 Bike Tire Inflator - Presta and Schrader Compatible Air Compressor Tool by Prestaflator by Mark Harrison

Purchased from Revain based on website video. Received it on November 13th and was immediately disappointed at the lack of instructions on how to use it with my bikes Presta valves. As a mechanic, I was embarrassed that there was nothing to press on the valve. After watching the video a few more times, I realized that I have to screw the adapter onto the valve, then press down on the adapter with one hand and operate the air valve with the other hand. If I was happy with a two-handed process, I would buy the product for half the price. Extremely poor description of this item on both Revain's website and the company's website. It was returned without trying.
