We reviewed the 8x42 variant and liked its slimline design and mostly pin-sharp images, making them some of the best binoculars for kids or beginners on a budget. They're waterproof down to 3.3 ft / 1 meter for up to 10 minutes, so we wouldn't recommend going diving with them, but you needn't worry if you get caught out in the rain with them. They're also fogproof so they'll cope well when moving between cold and warm environments.

Although their 42mm are advantageous for low-light observations, they're really better for wildlife spotting or general observation at dawn or dusk, so they wouldn't be particularly good for Astronomy. The best binoculars for stargazing tend to have a magnification of 12x and above, with objective lenses of 50mm and larger to drink in all the faint starlight.

In this Nikon PROSTAFF P3 10x42 deal, you'll also get a carry case and a neck strap, alongside the objective lens caps and eyepiece covers. We found the eyepiece covers of the 8x42 model disappointing as they don't seem to fit onto the binoculars particularly well, but for the price, it's not a dealbreaker. 

Their rubber armoring gives them good shock resistance (beneficial if you're buying for your child) and a good grip. They're very lightweight at 585g / 20.6 oz and can easily be thrown into your bag for a camping trip or into a large coat pocket.

If we are being picky, we'd have liked them to have the same locking diopter ring of Nikon's P7 and Monarch lines, but that's something you'll likely see when you outgrow the P3s and want to upgrade to a pair of the best binoculars.
