"Ultrafast Systems products are easy and intuitive to use. The technical and admin support before, during, and after the installation is truly excellent. We have a very-early generation Helios/Eos, a newer Halcyone, and an even newer Helios/Eos-IR. Even the ~12 year old Helios/Eos still works perfectly, and any time I've had a query (usually due to some new thing we're trying to do) the technical team has been very helpful, they've never said "No". I would recommend to anyone wanting to do ultrafast spectroscopy, the time and stress saved compared to building your own is immeasurable!"
