The PROS: Kinetic make solid trainers. This is the second I have had. Previously, I had their Rock and Roll trainer version 1, which was very expensive when I first purchased it, and which I sold recently, in order to buy the new "Smart" version. I didn't really enjoy the Rock and Roll function of my first trainer (the vertical bounce was very disconcerting, and the side to side sway doesn't really replicate the road feel, in my opinion). I was pleased that the new Road Smart trainer cost less than my original R and R (£149, reduced from the RRP). So, all good so far. The trainer is very easy to put together, is heavy, solid, bombproof. The fluid resistance feels very smooth, though I can never quite remove the tyre slip (same with the Rock and Roll), even though I am using a dedicated trainer tyre. This really only affects start-up or sudden sharp increases in power. Despite the hefty construction, the trainer doesn't make a huge amount of noise. Overall, the "trainer" part of "Smart trainer" is great - 5 stars. CONS: All the cons relate to the "Smart" bit. I can't get it to work! I was hoping to use this trainer on Zwift, but I can't even get it to work on Kinetic's own platform. The problem is that the black box (Inride pod) isn't being detected. I have now read tons of online accounts of this problem and hope I can find a solution, but until then, the "Smart" aspect of the Smart trainer gets ZERO stars. If I can manage to sort out the problem, I will update my review. [UPDATE: I have now got the Inride sensor to work, by making several changes. The main ones that I think made the difference were (a) putting a brand new CR 2032 battery in the Inride sensor pod, and (b) taking off the Inride sensor pod and re-attaching it closer to the drum/magnet, using double-side tape. When buying this trainer, the manufacturer or supplier attach the Inride pod and, unfortunately, they don't seem to always attach it directly in line with and close to the magnet. Now I have sorted this out, I am pretty happy using this with the Kinetic Fit app to calibrate the power meter, and with Zwift. Note that this type of "Smart" trainer does NOT change the resistance - but for this sort of money, it never would. When you hit hills on Zwift, you just end up going more slowly; it doesn't get "harder". If you want to make it feel harder, you have to change up a gear. Although I have increased the rating, I still only give 3-4 stars for the "Smart" functionality, because the tech seems glitchy. However, for the money I think Kinetic trainers are excellent value. I am now considering buying the T-6300 "Smart control" unit for this trainer, when I see one on sale.]
