Not currently an option I’m afraid.
Any suggestions you have though can be put in The Great Big Suggestions Thread which gets reviewed by the LH team and some of the suggestions have been implemented.
I very much doubt they will go through reviews to gauge the power though but maybe could list the wattage of different toys. Obviously though some toys apply their power better than others and the wattage wouldn’t tell you what the vibrations are like - focussed, rumbly, buzzy, etc. I’m afraid reading reviews yourself and asking questions on the forum is probably the best way even if it is time consuming.
On the old shopping site you could sort by most helpful review which was great for products where there are hundreds of reviews that really aren’t helpful! I miss that a lot, it’s much harder to find the more informative ones now.
