It has held up great for us. **Q: Does it work well on flat lawns too or do you need a hill for all the fun?** A: If you self propel then really a flat lawn is fine. We added a little liquid dish soap and it was very fast and fun. In my experience I believe that it will work on a flat surface but I havent tested that. **Q: How thick/durable is the plastic?** A: It is not thick. You can feel all the bumps, rocks, ect... underneath it. It seams pretty durable. I do not have any tears just minor nicks from rocks. **Q: Is this strong enough for a 12 year old?** A: Absolutely! Adults and a 15 year old male that weighs 200 lbs had a blast on this! ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great toy! Friends and family loved it! *by A***N on Reviewed in the United States on August 8, 2016* Such a fun toy! I attached some pre-party photos on account we didn't take any during because of all the fun we were having!Giant piece of plastic/tarp- Now I read some of the reviews and people say this is a huge piece of plastic or a giant tarp. That's not the case. I understand what it looks like but the material it's made out of is almost the same of a floatie or interior lining of a pool. If it were a tarp -it would be rough to the skin and not so slippery. It's very slippery when wet but add some tear-free baby shampoo and things get a little more interesting!When to use- I purchased this 50 foot slide for an adult "slip and flip" relay party we had last year. A combination of slip and slide followed by a small game of flip cup in order for your team mate to go next. We threw this party last year and our friends begged us to throw another one; so one year and a month later here we are about to have one this Saturday!Set up- My boyfriend and I opened the slide up and placed it to our liking. Once we had it laid out we use the anchors and tabs that came with the slide. I used Yellow duct tape to attach the tabs to the slide. Once we did that we then anchored into to the designated holes. (Don't pull the slide too tight while anchoring. Leave a little room for leeway.) It takes some patience to get it right. We didn't have an issue at all once it was completely anchored.How to use- Now my yard is flat so with this relay we all had to do a head start run before sliding. That's not Wahii Waterslide's fault that I was cursed with a flat yard but a hill would make things more fun for sure! We put a sprinkler in the middle of the slide for about 10 minutes to get it wet. We added baby shampoo before every relay. We placed the sprinkler at the beginning of the slide in the middle to separate the teams.Ruin the yard- We used our slide for about 5-6 hours on a scorching hot day and picked the slide up the very next morning instead of leaving it there. The grass was not ruined at all and we had some pretty heavy guests sliding across our lawn.I highly recommend this slide! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Strong and sturdy. *by V***I on Reviewed in the United States on August 21, 2020* From reading reviews the only thing I saw that was time consuming was set up. I watched a you tube video about using thin rope, using a large bolt to weight the rope down through the middle of the noodles, to string together $1 store noodles (I used about #20) and place those down both sides and at the end. I wrapped the sides of the tarp over and then under the noodles and it worked great! Adults used it too and the noodles made a nice side to keep the kids in and the end made a nice pool of water to slide in to. I used weighted 5 gallon buckets at the top corners and a long exercise mat between (1/2 on grass and 1/2 on the top end of the taro) so the kids wouldn’t accidentally get hung up on the edge of the tarp when they were running and that worked great too! The tarp does not need soap and is slippery enough. It was really fun! ### ⭐⭐⭐⭐ 4.0 out of 5 stars This product feels overpriced for plastic but it is multiples better than the cheap slide n slides that rip. Recommend. *by M***M on Reviewed in the United States on August 19, 2014* A lot of money for a piece of plastic and more time consuming to set up than 15 minutes; however this waterside is a guaranteed hit. No bones about it! We had used it several times with our child and recently used it at her birthday party. Four kids and one adult can actually go down it at the same time. We have a tiny hill but with a little running start a kid could easily slide the full 50 feet. A steeper hill would guarantee a longer slide. It is best if the hill slope is even on both sides otherwise the kids could slide off early on one side. So far the product has held up well and the use at the party was extensive but we have only had it for a few weeks. Every time we shut the water off at the party, an adult went back and turned it on for the kids. They could not stop using it because it was so much fun. Make sure to save some plastic room keys at hotels. I suggest using a few extra hotel size key cards and a hole puncher to tack in few extra times on the sides and bottoms of the plastic. This extra support is worth the effort. Kind of surprising the box doesn't come with a roll of gorilla tape. Duck tape is likely to not be successful unless it is a very high grade. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/763052-waterslide-50-feet-2-inflatable-riders-worlds-biggest-backyard-lawn](https://www.desertcart.sn/products/763052-waterslide-50-feet-2-inflatable-riders-worlds-biggest-backyard-lawn) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-01*
