I have used them over the last three years, my biggest ever spend was from them. Had to move to an external frame so got the rather pricey Savotta LJK for me its been worth every penny, I also have the Savotta 339 and love that too. Been using the Finnish ground mat in my hammock recently and I turn it upside down between the layers and it helps keep it in place due to its non slip surface. All in all I really like Varusteleka.
