Excellent service and very prompt…
Excellent service and very prompt delivery. I bought this cushion as I have a lot of pain when sitting for any length of time. I’d read the reviews and felt it was worth a try. I’m so pleased that I did! It’s been amazing. I used it on a recent 5.5 hour flight and for the first time ever I was very comfortable the whole flight with no pain at all. I used it on holiday in restaurants, again a God send. It folded easily into my tote bag and I could take it anywhere with me. I now use it everywhere I need to sit for any length of time. It’s especially good for long car journeys etc. I wouldn’t hesitate in buying again and can highly recommend both the item and the sevice and communication from the seller.

Great service and product
We decided to buy the rechargeable low light units in a six pack due to all the worries about power cuts. Didnt take long to fully charge and we must say very impressed with the units. Much safer than a candle in our opinion no naked lights. In our opinion good value for money and if the power outages occur we are prepared. They also have a movement sensor that is very effective and lights up the unit pretty quickly. Overall very pleased with product and service.

Although expecting disappointment I was persuaded to respond to the tv advert for storage boxes and order the special offer. They arrived in the promised time and proved to be all that was claimed in the advertisement. What a refreshing experience.
