Yes, even if you need time to think about making the purchase and end up buying it somewhere else, I would recommend the watch for those people that are especially shooting for 170+. For that range of scores, I don't think it's an exaggeration to say that each second really does matter. The watch helped me simulate real-testing conditions for all my PTs (take all PTs with scantrons and replicate real test-day conditions!) and was especially handy come test day since my proctor didn't give proper time benchmarks. I know many people say that it's cheaper to get a basic Casio watch and I did try that as well. In my experience, I got flustered trying to set back the minute/hour hands at the end of each section when you should instead be mentally preparing to get instantly back to the next one. All in all, one of the best purchases I made for my LSAT prep and wouldn't hesitate to make it again. I also heard about it through word of mouth since many people on 7Sage seemed to swear by it. I'm sure you can get more testimonies over there!

To clarify, this also isn't the watch I used and is brand new as stated (I got a spare just in case I lost it or something close to test day).

If you have any more questions, feel free to PM. Hope I helped!
