Verified purchaseI have chosen very good condition and the device is like new. No signs of use, everything included at a great price. I only buy refurbished e-devices - it's sustainable and good for the wallet. Delivery 3 days after ordering was also very fast.

Verified purchaseIt is our 2nd Ninja SL400 . This one is going into our motorhome. Because we didn't want to change and we only have a limited width for the Hlf, we now have 2 Ninja SL 400 Hlf. Delivery, item condition and price were great. Everything tiptop.

Verified purchasethe appliance arrived in perfect condition, 100% new, nothing to complain about except that the instructions and recipe book are missing, but they are easy to find on the internet as the price is very attractive. I wanted to try my first purchase of a reconditioned appliance and I was not disappointed.

Verified purchaseI bought the Ninja SL400 as "good" but I think the condition is very good. Well packaged and no signs of use. We try out everything diligently, great for baking 3-4 frozen rolls (10 minutes at 160 degrees 👍), it's not worth turning on the oven for that! Vegetables with salmon in the Airfryer are also great. I've also tried small cakes, which also turn out great, but for us it's something for 1-2 people 😉. The size is also just right for our small kitchen, the wide Ninja would be unfavourable. All in all, absolutely satisfied 😀

Verified purchaseHello, The Ninja SL400 (airfryer) is a fairly efficient appliance, especially for cooking white meat (chicken): it cooks quickly and the flesh is very soft. For Chips, it's not bad, but we're not at the level of a real Chip cooked in an oil bath. For the other vegetables, it's satisfactory, with cooking times that are still fairly short compared to a traditional oven, and power consumption that's certainly reduced because of the small volume to be heated. A generous volume for a very compact footprint (the two superimposed decks were our main criterion for selecting this model). We managed to cook a chicken weighing just 1.4kg. You can't get much bigger than that, but it's good enough. We really like the "Sync" function, which lets you programme a staggered start and simultaneous end of cooking for foods with different cooking times. We found it fairly easy to use, with simple, effective programming buttons. So we're satisfied for the time being, bearing in mind that we only bought it a fortnight ago and that we still have a number of programmes and cooking methods to try out. Antoine and Co.

Verified purchaseThe Ninja Airfryer in "good" condition was delivered very quickly and was still in the original box together with the operating instructions and a small cookery book. The Airfryer appears to be unused. It works perfectly. I can't see any scratches. Everything tipitopi. 👍
