    Fast delivery which was great. Quality of my refurbished Samsung s21+ was near perfect. Zero scratches or marks on the phone. Have had the phone about a month now and still perfect. The charging cable was not a fast charge cable but not a big deal as had one from previous phone. Would highly recommend backmarket.ie, and I will be shopping here again in future.

    Before buying, I had spent quite a bit of time researching the phone followed by lots of shopping round for the best prices. Coming up to and including on the day of Black Friday, prices seemed to fluctuate wildly, both up and down but in the end, I got the best price here. Ordering was reasonably easy although it did take two goes to actually pay for it. Delivery was several days later than was predicted but in my case that was not a major issue. Phone was, as advertised, in excellent condition. Transfer from my old Samsung was for the most part easy and automatic although did have trouble with WhatsApp. Battery life is disappointing with no more than 24 hours medium use but that seems to be the way and I doubt a brand new phone would be much better. Overall happy experience.

    Excellent all around. Site was easy to use and kept me informed of postal delivery etc. I got two o hones and they are both excellent. The description was right on the mark and I will be definitely using thus site again.

    I purchased the Galaxy S21 Ultra 512GB model in good condition and it did arrive in good condition indeed. Screen - mint condition. I'm very happy, only thing is I had to get a fast charger for it. Also, battery is somewhat average but in fairness I didn't expect it to be much better anyway (lasts about a day with medium usage). Shopping experience was absolutely fantastic 👌 💯 I would highly recommend this company to anyone.

    The delivery was extremely fast, it arrived at my address in 2 days... the quality of the phone is also great, practically perfect, the battery is not in such good condition but that's what you would expect from a used phone, apart from all that it's a 10

    He comprado un Samsung Galaxy S21+ al proveedor Tech Limited y cual no sería mi sorpresa cuando al abrirlo, el teléfono estaba en perfectas condiciones pero cuando lo enciendo, el modelo enviado es SM-G996N, modelo para mercado coreano, y no el SM-G996B, que es el modelo para europa y es el anunciado por el proveedor Tech Liited.. Muy decepcionada ya que, al leer comentarios de otros clientes, he descubierto que este modelo me dará muchos problemas, lo he devuelto. Confiando en Back Market y su prestigio, he hecho otro pedido igual que el anterior pero esta vez, con otro proveedor llamado ecomobile, pues me ha pasado exactamente lo mismo!! Back Market debiera controlar mejor la calidad que prestan sus reacondicionadores, que sean veraces en lo que ofertan al cliente, yo me aseguré de pedir los teléfonos que tuvieran el modelo correcto y así eran anunciados, solo para después llevarme la mala sorpresa de que no me llegaba el modelo correcto. Creo que mi confianza en Back Market ha ido de 10 a 3 en un par de semanas, me encuentro esperando el reembolso del primer pedido y ahora, si no hay otra solución, tambien temdré que devolver el segundo teléfono.

    Excellent quality and delighted I had the choice of a new battery which is not on offer in other refurb websites I visited. Very happy with my purchase and will be back.

    Phone Condition is excellent. Delivery was on time. Just that the cost was little expensive. Apart from price other services are awesome.
