Would recommend
This white caulk has a good color, which is very pure white. (The clear one is shiny). This caulk can be painted, and it stays flexible. I haven't used it outside, but inside I've sealed tub surrounds, baseboard, shelving edges, medicine cabinets, all with good results. It has almost no odor while curing. The cap is airtight, so I was able to re-use a tube months later - the first bit was runny, but the rest was still good. It does shrink somewhat, but not too bad. It adheres well to tile and acrylic latex painted surfaces. Would recommend!

good quality caulk
I like that is has flexibility to it. The tube comes in handy for small jobs. It appears to be good quality caulk.

Handy Product
Love how fast it dries, so i don't have to worry about anything touching it and sticking to the product before it cures. Nice, Handy product to keep around for quick fix jobs, that will last a long time.
