Turbo trainer help

Hi, I tried out Zwift yesterday but seemed to have a lot of issues with my speed not showing correctly after I had fitted a candence and speed sensor onto my bike (been meaning to fit one for a while now). After some more research, I’ve realised that I either need a power meter/reader, or a smart turbo trainer with the power meter built in. I’ve decided that want a smart turbo trainer, and I’ve been looking at the Kinetic Rock & Roll Smart Trainer II here is the link http://www.wiggle.co.uk/kinetic-rock-and-roll-ii-smart-trainer/

However, I know very little about turbo trainers in general, so any help would be greatly appreciated. Ideally I would like it to include the power meter and to get harder/easier automatically when going up/down hills in Zwift. would this one fit the requirements? I’m currently trying to do some research and learn about them, but it’s like jumping into the deep end of a swimming pool without knowing how to swim.

DC Rainmaker is where I go to compare trainers: https://www.dcrainmaker.com/?s=trainer

You could also get a single-sided power meter like a https://4iiii-innovations.myshopify.com/collections/power-meters/products/precision-ride-ready?variant=17034980038



i have a tacx vortex…brilliant for the money.does everything you need and can handle 950 watts and 8% climbs 

I use a Wahoo Power trainer (wheel off model) and find that it works well with Zwift.
