I 'll start with the `` pro '' \*\* it be lightweight compare to other similarly price projector . \*\* the lamp be incredibly bright , similar to what I would expect with a home theater class type projector . \*\* the construction do not feel cheap . it feel solid in you hand and \*\* when you flip it over or pick it up suddenly you do not hear and joint or seam creak like you do with some cheaper build plastic chassis projector . \*\* the outside look nice , be easy to clean and be firm to the touch . \*\* the control be extremely fool-proof . \*\* the `` keystone correction '' be great . no matter how high up , or down \*\* there be a lot of `` mode '' from blackboard to beige wall to white board to video to ultra bright . these might seem like silly extra perk , but they be truly invaluable in help you get it set up to look great fast . \*\* the definition for image up to 4-5 foot wide be INCREDIBLE . extremely high definition with incredible contrast . when you pull it back from the wall to go for something like a 6 foot wide image you will will notice fairly dramatic decline in definition , but the color still look great ! bright and vivid \*\* lot of plug in for VGA plug . no hdmus . I believe it can take up to three VGA plus and have a VGA OUT plug as well , so if you be use a desktop monitor , you can have what ever be show on you monitor also show on a monitor . it will let you bypass the projector when in conjuction with a CPU and let you continue to use you desktop monitor , you CPU , and all while project whatever you CPU or other device be tell it to . very nice feature I do not expect for this price . \*\* decent speaker . not incredible . good consider the money . \*\* nice free little carry bag and remote control -lrb- with battery ! -rrb- \*\* last and not least , this projector have two fan and they be both incredibly quiet no matter what mode it be in . they be also obviously quite effecient as well because when you turn the unit off the fan only need to run for about another 60 seconds to get the unit totally cool to the touch and then they power down as well . the `` con '' \*\* while it do have keystone correction it be only vertical , not horizontal . so you need to make sure when you be project that the projector be parallel with the wall . no horizontal keystone correction here . \*\* this be the opposite of a `` short throw '' or `` ultra short throw '' . this device be very much LONG LONG THROW . to get the size of image I be look for I need to have this projector about 12-17 foot away from the wall . \*\* when the in104 be on it put out quite a bit of heat . as I say though , the fan do a great job with keep it cool . I assume it throw off so much heat b\/c , for a projector in this price range , the lamp really put out a lot of light . \*\* as I say before , you need to get this thing pretty darn far away from the wall to get a nice big projection . the issue with that then be , a lot of you audience will probably be somewhere between the wall , and the projector . this be not the place to be as this thing have a crazy intense rainbow effect . I be normally not too sensitive to the rbe , but when I look back this projector when it be project the Disney movie `` Tinkerbell '' I think I be trip some major acid . it be totally psychodelic to look back at the unit in the middle of movie play . if super bright flicker light rapidly change color freak you out , you might want to spend a little bit more money and step up a model to one of INFOCUS `` short throw '' projector so you can keep that rbe in between the wall and the projector without you in the middle of it . \*\* the fan on this unit be big and powerful , and quiet to boot , but because of that , this unit spill a fairly substantial amount of light out of the fan duct . to I it be not distracting , but if you be really want a DARK DARK room for a home theater , it might be annoying . \*\* while the control panel be efficient , it be also very spartan ! this unit be all about just solid basics and not about lot of really cool bonus feature . \*\* no autofocus , which again , for this price range might be expect . the manual focus include a fast action `` course '' and `` fine '' focus though that be extremely easy to use to get a nice focus within about 5-10 seconds of initial focus manipulation . overall I would say this be great projector for the money . I be a public senior high math teacher and I think this will be great for use in a fairly bright room as the lamp be really powerful , however , the fact that I need such a long throw distance to get the image up to the right size be frustrating , and in hind sight I wish I have spend about 300-400 more dollar and get the same projector with a `` ultra short throw '' bulb and with a few bonus feature to boot on one of Infocus higher level model . as a projector for a large business\/conference room it would be great . for a large classroom it would be great . for a small classroom\/conference room I would not reccommend this unit . for a home theater for just a little bit of extra fun , in a nice big living room , I would reccommend it , however for a small bedroom or small basement room , no way no way . the color be incredible , the definition be superb , and even with fast action video I find there to be very little `` motion blur '' which be typically something that plague projector in this price range . all and all I would say it be the heart and gut of a unit twice the price , in a spartan wrapper , minus some of the nice bonus feature you might want if you be willing to spend twice the price . I give the unit a average of `` 4 '' star consider feature and performance for the buck !
