Wonderful product Wonderful product, no question. It helps a lot. The northern latitude here doesn’t allow for sunshine days for the largest part of the year and supplements are neither adequate nor safe as it is the case with other fat-soluble vitamins. Thanks for your care and support and sorry for the delay in writing my review.

As Described and Exceeds Expectations I've had the Vitamin D Lamp for about 1 week and am using it regularly. The product is exactly as described and exceeds my expectations. I do not have lab values to compare over time, so I'll be following how I "feel" over the next few months.

Great service Early days with the Vit B lamp (a week) but great service, dispatched almost immediately. Two day delay with stated delivery by UPS but regular tracking updates provided. Lamp delivered from US within 7 days. Almost bought from another source in the UK but dealing directly with Sperti and trusted courier was clearly the best and secure option providing 100% peace of mind. Possibly slightly more expensive but also best for after sale support.

I’m over 3000 miles away from Vegas I’m over 3000 miles away from Vegas, where these are shipped from, and I got it super quick, make sure you follow the instructions provided because you will very easily get a sun burn.

Yes! 🌞 We had snow in Berlin this past Monday, 1 week short of May 🙃… so, I bit the bullet and ordered the Sperti half-a-year earlier than planned. I’ll probably purchase the Fiji as well. I’m very grateful to have a healthier, more natural alternative to supplements! Quick delivery + the product was in perfect condition.
