Based on our own experience, this planting spiral planter umbrella digger is a game-changer! The drill bit is sharp and sturdy making planting a breeze. It saves time and effort, allowing us to plant multiple bulbs and seedlings effortlessly .The only downside we found is that sometimes it can get stuck in rocky or hard soil, but it's still miles ahead of using a regular shovel. Overall, a great investment for any garden enthusiast..
