I ordered two of these Gilmore sprayers via Amazon and received promptly.  Both units had air pressure leaks where the handle part of the unit screws onto the liquid holding portion; One sprayer air leaked moderately, the other unit air pressure leaked severely;  I was barely able to use the moderately leaking unit to do a "rush job" by very frequent pumping.  The severely leaking unit was not usable because it lost pressure so fast.  I called Gilmore customer service and requested a new unit and was told I would be sent a new replacement sprayer if I would prove recent purchase by sending them a copy of the concerned invoice via email -- I did this and quickly received a new identical replacement sprayer.  I immediately added pure water to the reservoir, operated the hand pump to pressurize, and immediately noted this new replacement sprayer also had a severe air pressure leak making it virtually unusable.
