Reviewed by Jacqui - 12th Apr, 2021 Deflates Had this now for just over a year. Only used a handful of times and now started to deflate. Contacted Berghaus who stated they provide a lifetime guarantee and only Blacks or Millets stock this item. Visited Millets for an exchange or refund and was told without proof of purchase they can not do anything. Disappointing customer service as these are the only stores to stock, lifetime guarantee so makes no difference on proof of purchase but no offer or exchange or refund.
