Prestaflator Micro CO2 Inflator Head – Ultra Lightweight 12g Precision Alloy CO2 Cartridge Inflator for Presta & Schrader Valves, Compatible with CO2 Pumps & Compressor Adapter

Small form factor and easy to use.

Went to use it and when trying to take it off the valve stem stuck inside the valve and the only way to get it off was to break the stem.

I REALLY REALLY wanted to like the Prestaflator Micro CO2 head. It's small. It looks great. IT DOESN'T WORK! I had a flat on the road a few weeks ago...an opportunity to use my Prestaflator Micro CO2 head for the first time. I wasted 3 CO2 cannisters trying to get it to work--and another one at home. I contacted Prestacycle. They promised to replace it at no charge. 3 weeks and 3 emails and a phone call later, I don't have a replacement and the company won't return my emails or my phone calls.Do yourself a favor. Avoid Prestacycle like the plague. I'm going back to my Genuine Innovations CO2 inflator. It's a little bigger and weighs a bit more, BUT GENUINE INNOVATIONS WORKS, PRESTACYCLE DOES NOT!
