GByou're getting off to a very bad start you're getting off to a very bad start. my order arrived today but there was no shipping notification, no delivery notification, no name or apartment number on package, shipped from a different state than the company is in and with a different company name so i had no idea who this was from. i live in an apartment building so the chances of someone else taking it were high. i had to take the chance of opening it to see if it was mine. finally when i go to your website to track and see if it is mine without opening, you have no tracking on site and try to get me to download an app. immediately after the purchase you sent an email so i could review my purchase and then proceeded to make these mistakes.

GBGot a new mountain bike and needed an… Got a new mountain bike and needed an inflator to go with it. Ordered the updated version of the inflator i have been using on my road bike for over 15 years and it met all my expectations. It may be a few extra ounces but the straight forward trigger mechanism works every time. Had the occasion to help a fellow cyclist repair a flat recently... their inflator was going through CO2 rather quickly but my GI inflator got the job done straight away... very reliable.
