Projector + free gift
For this price range by far the best option for a projector which is easy to transport and has a build in speaker. Because it is so compact the fan works extra hard and you can hear it. While you whatch a movie it doesn't bother but if you want to use for any use without music it might be annoying. Other than that 5/5. The quality is really good

Great projector for size and price.
Great projector for the price. Being able to automatically adjust the keystone and size is great. I have a cheap portable screen that makes watching outside when its dark enough great. I can see it working great for camping or whatever.

Thank you for your inquiry regarding the Poseidon E40 projector. The maximum focus distance for this model can vary depending on the screen size and throw ratio. The maximum screen size we recommend for projection is 120 inches at a distance of roughly 3 meters., but we recommend testing it to ensure it meets your needs.

Great projector and best aftersale service
I want to correct my previous review.
My unit was defective and after the after-sale service replaced my projector, the new one maintains all the virtues and corrects the problems of the first one.
The attention has been great.

I am really satisfied with the performance of the projector. Both the image and the sound are really good, even in not entirely favorable conditions, the layout of my room forces me to a lateral projection, and also with a vertical tilt, this undoubtedly affects the focus of the image, but the ultimea poseidon e40 solves the situation without problems, as can be seen in...

Thank you so much for sharing your positive experience with the Ultima Poseidon E40 projector! We're thrilled to hear that it has exceeded your expectations and performed exceptionally well, even under less-than-ideal conditions. It's great to know that the image and sound quality have impressed you, despite the lateral projection and vertical tilt in your room. We understand that the layout of your space can sometimes affect the focus of the image, but we're delighted that the Ultima Poseidon E40 has effortlessly solved this issue for you, as evident in the videos and photographs you've shared. Moreover, it's fantastic to hear that you've pushed the specifications to the limit by projecting a 130-inch screen, surpassing the recommended 120-inch limit. We appreciate your understanding that this may impact brightness, but we're thrilled that you're still satisfied with the result. It's impressive that the projector provides sufficient image brightness even in daylight conditions, without requiring complete darkness in the room. Your recommendation means the world to us! We're thrilled that the Ultima Poseidon E40 has enhanced your movie and series viewing experience to a whole new level. We're here to help and ensure you continue enjoying your entertainment to the fullest!

Good but with buts...
The projector gives a great image. And I had doubts about the sound, but it is powerful and very good. In the basics, image and sound, no problem.
Apart from that, the automatic image adjustment does not work as well as one would expect and in fact tilts the image (perhaps the product that I received has a small defect). But it's not serious because I think it's bett...

Please reach out to our customer support [email protected], and they'll guide you through the troubleshooting process.

We were looking for a projector that does not take up too much space, looks aesthetically pleasing without having to compromise on functionality. With limited space right now we decided on getting a projector instead of a TV on a budget and we have found the perfect projector for us.

After many attempts, I connected it to the BT speaker. Cinematic experience. Android works pretty smoothly. Autofocus too. Handle is helpful to adjust the angle, no need to shim anything.

From the moment I unboxed it, every single detail, from its sleek design to the robust build quality, just screamed top-notch.

Thank you so much for sharing your amazing experience with our Poseidon E40 Projector. It's truly delightful to hear how much you're enjoying it and how it has exceeded your expectations in so many ways. We're thrilled to have provided you with a top-notch product that brings the joy of a mini cinema right into your home! We appreciate your feedback regarding the power supply and the autofocus feature. We understand that the bulky power supply may seem a bit out of place with the sleek design, and we apologize for any inconvenience caused. As for the autofocus feature, we're sorry to hear that it doesn't remember its settings. However, we have a handy tip for you! You can save the focus settings by simply disabling the auto-focus and auto-keystone correction functions. This way, you can avoid the hassle of recalibrating it every time you turn on the projector. We're glad to hear that these minor inconveniences haven't dampened your enthusiasm for our projector. Your satisfaction means the world to us, and we're thrilled to have made a positive impact on your home entertainment setup. Thank you for recommending our projector to others who are in the market for a top-quality device.
