I was a bit unsure of what to expect given the cost of the item but I can honestly say I’m super impressed by the quality of it. I knew it included a backpack to store everything in but I expected this to be cheap and needed to be replaced. It’s actually really good quality and has straps and pockets inside so that the content doesn’t move around in the bag. You can tell by the feel of it that it’s going to be really durable, this gives me a lot of confidence that the telescope won’t get damaged in transit when my son is off on his travels with it.The instructions are really simple and very clear, it’s super easy to assemble. Each element of the telescope is well crafted and I expect that it will last a very long time.I 100% recommended this telescope for beginners and experts alike. ### ⭐⭐⭐⭐⭐ Easy to assemble and use - great product for the price *by S***5 on 8 January 2022* The telescope arrived boxed and contains a handy carry rucksack with all parts wrapped in bubble wrap inside. Unfortunately there were no assembly instructions included but a quick search on U tube found a easy to follow presentation. It's very easy to put together. The tripod is a bit wobbly but it soon steadies and is lightweight. Good starter telescope for viewing the night sky and simple to get good results. ### ⭐⭐⭐⭐ Greater starter telescope *by H***R on 29 May 2023* The telescope is light and easy to assemble. Ideal for a novice like myself. --- ## 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.tn/products/285239246-oys-telescope-70mm-aperture-400mm-az-mount-beginner-telescope-adults](https://www.desertcart.tn/products/285239246-oys-telescope-70mm-aperture-400mm-az-mount-beginner-telescope-adults) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-04*
