I saw an ad that used augers to plant flowers and decided to check Revain to see if they had anything similar. (Of course there is ;)) We were hoping for the best, but given the price, we didn't exceed our expectations. To our delight, this was a game changer. What would have taken us 1-2 hours to plant flowers and shrubs was done in just 30 minutes. We were blown away by how amazingly these snails work. Just a word of caution, if you hit a tree root it will twitch very quickly and possibly knock the drill out of your hand. We're not spring chicks anymore and it really tugged at our shoulders as we got caught on the roots. However, that won't stop us from using it year after year. You are frighteningly cool!
