Markuswrote a review of e*thirteen components TRS Boost Wheel - 27.5+ on October 22, 2019
Bought these to replace some low end WTB wheels. I have to say I'm impressed. Been on them for a year now with no issues. I'm not super heavy (170 lbs) and run 28psi in the rear so not super hard on wheels. After checking the E13 website it looks like these are their Base level wheels, which come with sleeved rims and 6061 alloy. While good for most people, if you're heavier and like to run low pressure with thin sidewall tires, the Plus level wheels might be more for you (stronger 6069 alloy and welded). I think maybe the previous reviewer should up his tire pressure a bit! 25 psi with Exo sidewall is begging for dents in rocky terrain.
Overall for the price I think these are great. Highly recommned!
