One of the standout features of the Upclose G2 Porro Binoculars is their multi-coated optics. This ensures that you get clear and bright images, even in low light conditions.

However, there are some downsides to the Celestron UPCLOSE G2 Porro Binoculars that are worth mentioning. Firstly, the field of view is quite narrow, making it harder to locate and track moving objects. This can be a significant issue for bird watching or other activities where quick movement is required. Additionally, the focus wheel is not very precise, and it can be difficult to get a sharp image at higher magnifications. 

Another issue with these binoculars is that they are not waterproof, or fog proof, meaning they are not suitable for use in wet or humid conditions. This can be a significant disadvantage for those looking to use them in challenging outdoor environments. Additionally, some users have reported that the image quality is not as sharp as they would like, particularly at the edges of the field of view. 

In terms of value for money, the Celestron UPCLOSE G2 Porro 20x50mm Binoculars offers decent performance for their price point. They are a great choice for those who are just starting out with binoculars and want a reliable and affordable option for general use. However, more serious bird watchers or outdoor enthusiast may want to invest in a higher-end pair of binoculars with better optics, wider field of view and weatherproofing. 

Overall, the Celestron UPCLOSE G2 Porro Binoculars are solid choice for those on a budget who want a decent pair of binocular for general use. They offer good image quality, comfortable grip, and a light weight design, making them a great option for bird watching, hiking, or other outdoor activities.
