Well worth it!
Caulking isn't new to anyone, but for the homeowner or renter who occasionally needs a bit of caulk and wants it ready to use at a moment’s notice, this is the product to reach for. Unlike traditional tubes that require squeezing and can be messy or inconsistent, this applicator features a push-button mechanism with adjustable flow control—making precise application effortless and clean. The design is intuitive and ideal for small touch-ups or quick fixes around the house. While it may come at a slightly higher price point, the convenience, reliability, and ease of use make it a worthwhile investment for anyone who values having the right tool on hand when needed.

This stuff is great!
I am a 74 yr old woman who has never caulked anything in my life. This was so easy to use and it works great!

Not totally clear
Does the job but it dries kinda yellow, not clear. But should be ok once it’s painted.

Great Product
This product is a fantastic find! It's reasonably priced, making it accessible for most budgets without compromising on quality. The product is exactly as described, and its usefulness cannot be overstated. I've found it to be incredibly practical and efficient in meeting my needs. The attention to detail is impressive, and the performance is on par with more expensive alternatives. If you're looking for something reliable, well-made, and at a fair price point, this is the perfect choice. Highly recommended!

Still leaking…
I’ve used this twice and my bathtub is still leaking…. It was easy to install but I’m going to be removing and going back to old school bathroom tub and tile caulk.

Easy to use.
Easy to use. Needed to seal a baseboard in a wet area. Application was easy and so far is holding up very well.
