cock ring advice

Hi I am new here but am looking for advice on cock rings as i used to have one that was amazing since then i just haven't found a good one. So who here has experience of using one from lovehoney and can anyone recommend one that they have used just i found the other ones i have brought elsewhere do not do what they are supposed to and stop the blood from leaving basically they been crap, I wasn't able to keep the amazing one i had as my new partner wanted me to throw away everything i used to have as it was with a different woman. Any help would be greatly appreciated.

Do you have preferences in respect of materials (inc stretchy or solid) vibratingness etc
