Pros
Pro Comes with a battery
The projector is usable even when there is no power supply provided. Though its worth mentioning that you only get 160 lumens of brightness (half of the maximum) when running the projector on battery. The battery lasts for about an hour, which should be enough in case you need to give a short presentation with no power outlet available.
Pro Very portable
AAXA P300 is extremely light, weighing only 0.97 lb, making it easy to carry around. It is also very small in size, only 1.5 x 5.9 x 3.8 inches, making sure it will fit in a suitcase.
Pro Everlasting lamp
The LED light source lasts much longer than regular projectors, estimated at around 15000 hours. Technically, the lamp will not need changing for the next 10 years, if you use the projector for 4-5 hours a day.
Pro Large picture for a small projector
It has a throw distance of 5-12 feet and an image size of 50.5-121.3 inches. You can place the projector close to the screen in a small presentation room and get a decent image with the size of a large TV.
Pro Usable in ambient light
As a business projector, AAXA P300 is bright enough to be usable in presentation rooms with ambient light, in fact it is one of the brightest portable projectors out there.
Pro Great variety of inputs
It has many inputs like HDMI, VGA, MicroSD, USB and AV, making sure the presentation is not delayed due to connection issues.
Pro Very good picture quality
BenQ TH670 has a resolution of 1920x1080, producing a detailed Full HD picture. It has a white brightness of 3000 lumens so it's bright enough to deal with ambient light in a family room.
Compared to other inexpensive HD projectors, the TH670 has the best contrast. A contrast ratio of 10 000:1 means there is a reasonably large difference between the blacks and whites this BenQ projects on the screen. This helps create a life-like picture. The contrast ratio (as for TH670’s competitors) is boosted by BrilliantColor technology. Unlike its competitors, the BrilliantColor can be disabled. This lets you choose between a high contrast or better colors, depending on the content.
Pro Quiet fans
The fans produce 29 dB of sound in Eco-Mode. In normal mode the noise-level is 31 dB. From a few feet away, you can not even hear it.
Pro A fairly long-lasting lamp
It has a lamp life of 4000 hours in Performance Mode. If you use it in Eco-Mode only, it will last up to 10 000 hours. In case the lamp dies or you want it to be as bright as new again, a replacement lamp costs $199.
Pro Works as a business projector
Though the TH670 is a great home cinema, it also does well as a business projector. It delivers a very detailed picture with clear content. Even very small black text (5-6 points) on a white background does not get blurry and can be read easily.
Pro Light and small
The projector weighs only 6.6 lbs, so it is easy to transport. It measures at 5.4 x 12.8 x 9.2 inches, making it is easy to store when you are not using the projector.
Pro 3D support
The projector has 3D support, though you will need to purchase suitable 3D glasses since they are not included.
Pro Back-lighting on the remote
The remote has back-lighting on its buttons. Since projectors are used in a dark room, this comes in handy.
Pro Low input lag for gaming
The input lag is 33.1 in game mode, 33.9 in cinema mode, and 35.2 if you turn on Brilliant Color. In other words, the projector is suitable for competitive gaming.
Pro Great built-in speakers
It has a 10W built-in speaker with clear and loud audio, so external speakers might not even be necessary in a small room.
Cons
Con Poor colors
This is not the best pick for playing video content due to its poor colors. P300 is meant for presenting slides.
Con Noisy fans
The fan on AAXA P300 is rather loud, it's comparable to an overheating laptop.
Con Complicated setup
There is no lens-shift for easier setup, so you have to be careful when first installing it in the room. Though it does have zoom-lens of 1.20:1.
Con Not great for 3D
If you want a great 3D experience, an inexpensive HD projector is not the best option. You will need a large picture size for a good 3D effect. TH670 will have a dim picture if you make the screen large and view it in 3D.
