We purchased this gate because of the option of extending it and the fact that you don't need to screw it into the wall. The two previous gates I'd bought for my hallway had been useless and not particularly safe as they screwed into the wall and came loose after around a month of use, though neither of these were from the Babydan ranges.
We've had this gate now for well over a year and its exceptional, we've only had to tighten the nuts once after so much use and it doesn't lose any integrity when you add the extensions, it stays solid with no wobble, which had worried me previous to buying. It may be a little more expensive than most gates on the market, once you add the extensions, but its by far the best gate out there.
Especially if, like me, you need it for a larger doorway or area. We use ours across our hallway as we have two steps in the middle.
great buy that has lasted throughout my daughters baby years and will no doubt last through my 7 month old's. I highly recommend it.
