Customer Rating: Summary: Outstanding hose Comment: This product works great. It connects a standard tank to the baby weber grill. Customer Rating: Summary: Finicky, fussy, and flaky Comment: Even after following all the tips and suggestions made by other reviewers, I've been unable to get reliable use of the hose. I follow each step (turn this off, wait, turn this on, wait, turn this off, yada, yada) and it only works some of the time. The next time I cook, I have to go through the whole routine all over again. I just don't have this kind of time. Customer Rating: Summary: Propane hose Adapter Comment: The merchandise works well with my colman camping grill and a 20 lb. propane tank. Customer Rating: Summary: Ruined in 1 month Comment: Buy this hose only if you have no squirrels or other rodents where you live. They bite right through this Weber hose, they ruined mine after just 1 month of use. A far better product that does the same thing is the Freedom Grill FG-50HA hose. It is stainless steel braid hose, and animal proof. It is slightly shorter, but still plenty long enough to reach from the Q grill at table height to a 20 lb cylinder on the ground. Thanks for earlier reviews that point to the FG-50HA. I bought it and it works great with my Q. Customer Rating: Summary: Doesn't work with Q 300 Comment: There's no mention of this in the product description. This product won't work with the Weber Q 300 Grill.
