Used bailing wire on the battery , hated using it . I have another velcro , might use it . This one looks better than the first , this one has white insert shelf . I ordered 3 more back packs with no pump to make 3 more of these . I can replace the battery in 1 minute and keep on working . Replace the pump in 10 minutes and keep on working . Nothing else like on the market , it's a no brainer . You can put any pump or battery you want in it , versatile . What do y'all think ?
