Anybody try one of these split air units yet ?

Just was wondering if anybody has any feed back on these split air units on E-bay ? They have several units and brands in different sizes, 9000 btu, 1200 btu, 1800 btu's some around 6- $700 range. Was hoping I wouldn't have to bite the bullet on one of these but looks like I need one for my new room soon with mid day temps pushing my room to 99 f today had to dump the room and co2 with my exhaust fan get it back down to 90 f. so far plants look ok for the second time this has happened , be ready to start flowering in another week, would like to harvest before having to do the work in the room. May cut the Co2 and turn on the vents and run the room at 75-80 range to finish up seems safer....................... anyway its my first grow go figure having bunch of bugs to work out. any feed back would be appreciated thanks

if anything keep the air moveing alot better safe than sry how many lights do you have

Do you have a vented hood? Cool tube? Get a temp controller. It has an outlet and a temp probe so when the tent temp gets to a certain point it turns on an exhaust fan
