I purchased this life jacket in January and, although I have (fortunately) not had the opportunity to use it in a real emergency, I have used it several times. The materials and workmanship are excellent and the jacket is very comfortable to wear, despite being an offshore jacket, which is bulkier than many other “coastal” items (the jacket has a light, a built-in hood and can easily accommodate a PLB). For a more in-depth analysis, look for the Yachting Monthly review published in 2022.
There are only two “issues”: the backtow system does not appear to be all that easy to be repacked if the jacket has been activated and the system deployed. The manual is not very clear on this and the videos on the TemO website refer to older and different versions. I hope TeamO will address this by publishing an updated video for the current system. Otherwise, it would probably be a wise idea to open the jacket and record a video showing how the system is packed for future reference.
The second issue is due to Brexit: if, like me, you plan to buy this life jacket from abroad, be prepared to pay very high customs duties. It's not TeamO's fault, clearly (they seem to try to keep prices low), but if you end up paying 30% more than the listed price, other products might become more interesting. Of course, you'll have to give up the backtow system as TeamO is the only manufacturere to offer a similar solution.
