"I experienced your service as very nice. The people at Altitude Dream think along with me to find a tailor-made solution with the corresponding specific wishes and experiences. When I used my Altitude Dream tent in 2008 as preparation for the Olympic Games, it caused an increase in both haemoglobin and haematocrit and I won Olympic gold. "

"Very correct and quick response when I had a problem. Definitely recommended, because the device was in another room no noise. I think a positive effect on my performance. "

"It was a first test for me to see if I would benefit from a high altitude cure in preparation for my important races. There was little effect on my blood values (haematocrit, reticulocytes, etc.). However, after less than two weeks in the altitude tent, my training went very smoothly and the values I was pedalling and running were promising. So there was undoubtedly a clear positive effect my performance. Test passed. Furthermore, punctual delivery and collection. Thanks a lot! "

"I felt very good the week after the tent and I am currently on training camp and also feel pretty good and have seen improvements in my performances on training. The service was excellent from the delivery, set-up and follow-up to return. The machine had no defects and worked well. The altitude tent itself is fine, but it gets rather dry inside and when two people sleep in it you are always awoken by the other person unzipping the tent to go to the bathroom, get up for work, etc. "

"Before and during the "altitude training" I had my haematocrit determined, which eventually went from 39 (before) to 43 (after), so probably a pretty positive effect. Unfortunately, I did not take any extra iron during this period, perhaps the effect would have been even greater. The installation of the high tent went very well, I did not have any problems during the rental period. The return of the tent was also done according to the agreement. Sleeping in the tent was not too bad, maybe I was lucky that it was not too hot outside. The most important thing of all is that I was able to qualify for the Ironman in Hawaii, which was the ultimate goal. So I will probably rent a high tent again, I think mid August to end of September, I will keep you posted. "

"The service from Altitude Dream was excellent. I am convinced that the use of the height tent has contributed considerably to my successes. This way I became Dutch champion in my age category in both the entire triathlon and also in duathlon. "

"I felt the effect enormously the first time when I had slept in the altitude tent for a month and then left on a cycling trip some two weeks later. I trained very strongly then, both cycling and running. The second time I slept in it as a preparation for my Ironman in Mallorca. Again, I will certainly have had an effect, but then I had also trained heavily the 3 previous months. The first time, I had trained very little and still had a strong stage. Soon I will sleep in the tent again, again in preparation of my cycling training in Mojacar at the beginning of March. I have no negative comments about your service, on the contrary. You come when it's best for the customer (even later in the evening). The installation is quick and the explanation is clear. Even if there are questions later, the customer can come to you. "

"Service more than fine !!! This was only a test phase. In addition, I cannot experience it at upcoming competitions + training courses as these have all been cancelled. "

"No problem. Your system has already done its job well with a PB of 10h12 and a KONA slot!!! "

"From the start, everything went very well. I think I have been, somewhat accidentally, a demanding customer due to the move to Italy, and I have always been perfectly served. Fast delivery, good tips. And emails with questions are answered quickly. By making mistakes in my preparation, the races in 2015 were a bit disappointing. There were no real top performances. So I can hardly estimate or determine the effect of the altitude tent. I assume that 2016 will be a top year and that I will be able to gain some extra percentages by using the height tent. "
