I live in urban areas in Hong Kong under heavily light polluted sky and the faintest stars I can see with naked eye is only up to 1.5mag. This is my review based on 4 to 5 nights of usage after receiving the scope for 2 weeks.The package is double boxed and arrived safe. Tested the collimation and it's only slightly off center after traveling half of the Earth to reach home.This is the first Newtonian scope I own so I take some time to take it all apart to understand how every part works, adjusted the collimation, made small improvements such as painting the edge of the secondary mirror black to help improving contrast and added setting circles to both axis to help "push to" objects quickly.I prefer not to use the red dot finder even it fully works because for bright objects, putting in a 25mm eyepiece (from my previous scope) got a magnification of 16X which is already a good "finder scope" range of magnification for me. And for any dimmer objects, red dot won't help much so I better locate it using an Phone app + the setting circles.The scope and mount is very light weight compared with any other 4 inch telescope setup so I can easily bring it out to any location just packing everything in a single backpack, and carry a photo tripod on my hand. Setup / pack up only take less than 5 minutes so it's very efficient.This is my second telescope, the first one I owned is Nexstar 4SE with a similar aperture of 102mm but a much longer focal length of 1325mm, and is a Maksutov-Cassegrain.As I compared the image quality with my old scopes which is also 4 inch, I can say both of their optical performance are similar under the same magnifications. I had viewed the moon which is bright and clear, the stars as pinpoints with slight diffraction spikes for those brighter ones, and even Neptune can be spotted as a dim blue star light dot. The provided eyepiece are OK and very light weight but provide up to 40X magnification only. So later I'm planning to purchase a better quality one with 4.7mm to push up the magnification to 85X so that I can continue my review on Mars / Jupiter / Saturn.For a 4 inch scope, I can say it's performance is pretty comparable with any other more expensive 4 inch refractors / catadioptrics and I'll recommend it if you know what to be expected for a 4 inch scope.

Sharp, good colors, good dynamic range, and does well in low-light. Plug and play worked perfectly with Ubuntu Linux. Even the silly stick-on privacy cover works very well. The cord has ample length, and the camera is mounted on a ball joint for extra adjustability.The only issue is the autofocus-- it has to go blurry and then re-find the focus every time you move. The effect isn't too dramatic, especially if you're being displayed in a small window in a video meeting, but it's still annoying and something to take note of.

Using this on my PC for gaming and streaming.Sound quality is great, there's no noise.Cord length is nice, I wouldn't be able to use this on my PC if the cord wasn't as long as it is.Comes with a nice pouch to keep it in as well.

Great (and cheap) product. Got it for my Bose speakers. Looks fantastic because of quality power coating and you can hide the wire inside the pole.

Favorite gaming headset, I've bought several as gifts for friends and myself, and they have held up even over a year! No problems at all, very good, especially for the price you pay! Definitely cheap in price but not in quality, will likely be buying again soon, all of my friends want my headsets! Also has a nice long cord!

This is actually a lot better than I thought it would be the only negative about it is the buttons and knobs feel really cheap but hey. you get really great quality so who cares?

I can't really think of anything negative to say, it does exactly what you would want it to. It works perfectly, and the connection is stable. I assume the picture quality is a perfect transmission.Idk what to say I bought three products like this at the right time and this is the only one that works well so I guess it gets my endorsement

I primarily use this for vocal recording for musical composition. Overall, this mic has been great, and catches just the right amount of my voice without any external interference. I sometimes have a fan going on low speed about 5 feet away from me, and it doesn't interfere, even while blowing on me. To be fair, I have a foam windscreen on the mic itself. I can recommend this to fellow musicians for a home studio. I am sure it may not be as good as some of the higher end brands/models, but this one works for me.Studio:FL Studio 10M-Audio Firewire Solo Recording InterfaceBehringer Studio Headset
