"I've been doing business with Alle van Calker and Sunvalley Solutions Inc for approximately 15 months. During that time, Mr. van Calker has provided impeccable customer service and excellent advice to our research team as we assembled soil sampling equipment for a project in Gabon. In particular, he's been extremely helpful in getting our orders processed and shipped on short notice, always providing sound information on the best shipping options. To this point, Sunvalley Solutions Inc has been our primary source for soil sampling equipment made by Eijkelkamp. With one exception, the equipment we've purchased from Eijkelkamp has been of exceptional quality constructed of high-quality stainless steel that has held up extremely well under harsh conditions. We've used Eijkelkamp equipment primarily to collect intact cores from soil pits for determination of bulk density. The equipment is easy to use and allows us to extract cores with great precision. When a weld failed on one of the augers we purchased, Mr. van Calker didn't hesitate to get us a free replacement. We look forward to doing continued business with Sunvalley Solutions and taking advantage of Mr. van Calker's expertise in matters related to the import/export of scientific equipment."
For the last several years, Sunvalley Solutions Inc. has been our environmental monitoring go-to supplier for a plethora of applications: Soils, sediments, in situ tests; Water sampling and testing; Earth and Sludge and Slurry monitoring/measuring. Sunvalley is always responsive and readily helps sort out questions to ensure we provide the optimal application solutions. and their equipment is the best, always meeting or exceeding specifications presented. SunValley's management has been in the industry for decades prior it's founding, and this depth of experience shows itself in each transaction. I recommend the company enthusiastically.
Sunvalley Solutions Inc. completely came through for me in my time of need. As a graduate student in Alaska, I only have a few precious months to collect all of my data for my thesis, so timely shipping is extremely important. This spring I needed Rhizon soil moisture microlysimeters, and your company was the only place I could find the amount I needed in stock and able to be shipped to Alaska by early May. To make the deal even sweeter, your prices were also lower than two other major competitors. All of my interactions with Alle van Calker were extremely pleasant, and he came through for me when I was in a bind.
Over the course of the summer, the Rhizon samplers allowed me to collect soil moisture 5 times over the span of 4 months, and I hope to have enough data to graduate on time this spring. Thank you for your support!
We had quite a tricky task and the way you approached it, was really helpful, the equipment was just the right match , very reasonable pricing, and excellent service. Follow through the entire project , right on and just a pleasure working with you.
