YJINGRUI 15,000VPM Cordless Tile Vibrator - 6-Speed Adjustable Tiling Machine with 16.8V 10,000mAh Li-Ion Battery (2-Pack) - Perfect for Floor & Wall Tile Installation, DIY Home Renovation Projects

There’s only one thing I can say about this tile vibrator: I wish I had it a year ago. That was when I replaced the tiles in a bathroom in my house. It came out good, but this gets a professional result in much less time. All the manual vibration is time consuming, and you may not always get that professional look.I’m now doing the same thing for an entire kitchen and for my first day of working using the tile vibrator, I can tell that the result will be even better than the bathroom.With two batteries, you can work the whole day without worries. When the first battery runs out, use the second one and set the first to charge and repeat. It is heavy duty and good overall quality.I've laid tile in my kitchen and guest bath with varying results, so that's the perspective I'm bringing to trying this out while tiling my master bath. The suction cup holds the tile while you position it just...so...and then the vibration function helps you collapse the grooves in your thinset without bubbles so you can lay the tile flat on the first try.Having 2 batteries is a nice bonus, since you can recharge one while using the other. Our bathroom isn't big enough to need more than 2 batteries, but it was a nice thing to have nonetheless.This vibrator works good and made my tile job easier. It did give my arms a workout but the results were well worth it. 5 STARS
