Both the swift Swift Dolly (SWFT-DL) and the 32mm camera Dolly Track (P-SFT-DT-12) track were very well machined and close to perfect. These products have really surprised me, in a good way! I would have given the equipment a full 5 stars, but didn't as I had a bit of trouble using my carbon-fiber Gitzo tripod to fit in a low sub 100 cm position. If I needed it to go higher than 100 cm then that was not an issue at all. I found that my older "190 art series" Mafrotto tripod worked fine a this low 90-100 cm level. Again I am nit-picking here as there are always "work-arounds" for most issues. As a still photographer using this (Dolly) product, I think, in the future, they should be able to tweak the tripod slot-design to accommodate more tripods that still photographers use. Yes I am a "niche-case" but it is an easy fix in my book. To be clear, this is a product for film makers and videographers, so using a quality deditcated video tripod should be lot easier. Maybe a short Bazooka would probable fix this too. I could not use one as I have Syrp's "Genie One" attached to the base plate of the dolly. Although, I was not able to obtain one to test, I am certain a quality video tripod you won't have any issues at all. Finally, these two items are very good products and the people at Proaim REALLY went out of their way to respond and remedy my issues. Excellent work!!!
