i just got this Dunlop conditioner, and used it one time on one guitar, and it is very good stuff. i didn't know that it came with the liquid and a sponge type applicator on the bottle, so when I used it the first time it was like using one of those glue pen type units. The conditioner oil really gets soaked into the wood, and it is not messy to use at all. I got my guitar to play very nicely, and will use it more and more on other guitars, and see how it holds up. It shouldn't have any problems though as it seems to be designed very well. Highly recommend buying for the price, and your guitar will thank you as well!
