Still doing an excellent job after ~3.5 years
1) This product provides great value for your money. It helps so much with yard drainage and costs very little. 2) It's so durable. I've been monitoring it for about 3.5 years now, and it has withstood all the sun, heat, and thunderstorms nature has thrown at it. Also, it has never caught the blade of my lawn mower, which has probably passed over it around 100 times now. 3) The rounded interior contours, internal ribs, and high-density polyethylene (HDPE) construction contribute to the overall strength of the product. 4) It's so simple to install if you've done your measurements in advance. 5) Cleaning the product is easy, although I've almost never had to over the years. But it's just as effortless to remove this product from the pipe as you might expect for something that stays embedded in your lawn all year long. 6) The emitter pops up just like it's supposed to during heavy storms that cause copious drainage. When installed properly, this product performs extremely well.

High-Quality and Reliable Drain Cover
This drain cover is of very good quality and has worked exactly as I expected. It feels sturdy and well-made, not flimsy like others I have tried before. It fits properly and helps block debris effectively, which keeps the drain cleaner and reduces clogging issues. I also like that it is easy to place and remove whenever needed, making maintenance simple and quick. The material seems durable and resistant, so I believe it will last a long time even with regular use. It is a practical and reliable product that does its job well.

NDS Pop-up Drainage Emitter
Received promptly and in good condition. Easy to install and functions well. Used to divert eaves rainwater to a garden bed affixed to the end of a buried drain pipe. Recommended.

New version and old version
My previous version of this item was manufactured with a spring loaded pop up lid. Works great. We will see how this version makes out as it has no spring. The spring just kept enough tension that when i went over it on mower the lid did not raise. Just FYI

Allows for a large flow of water
Pops up easily. This design allows for a few leaves to come out when raining. I don't have a lot of large trees so I don't know how it would handle that situation. I am able to remove it during the winter season so it wont freeze shut. Overall, a good product.

Works great
Trenched and placed 15' of 4" PCV out into yard getting the downspout flow away from the foundation. The pop-up emitter works great to release the rain water. Heavy rain areas might need longer length drain pipes. Make sure you have a slight decline in the pipe for flow (check with a plumber). Make sure the the emitter is low enough so lawnmower won't hit. Would buy again.
