My son has used these and they do help in protecting the thumb jams. Unfortunately, no glove manufacture seems to understand that goalies are continuously getting hit in the hands and thumb area with 100+ mph balls. This can limit performance. Would goalies pay more for gloves that protected their hands, you better believe it. Manufactures please make a great glove that will keep the bones from breaking and thumbs from jamming and the manufacturer that does this, will have the only glove worth buying. Until that time the STX Cell V Lacrosse Goalie Gloves work a little better than the countless different gloves we have tried.
