## Customer Reviews

### ⭐⭐⭐⭐⭐ Make sure it's perfectly aligned at installation
*by A***R on December 13, 2014*

The product is well built, but the ease of closing it depends on installation. The two sides need to align perfectly. This is more tricky than it seems because the sliding window might not be flushed with the frame bar. In such case, add a shim to make it flush. Alignment issue is the reason why phillips screws are included in addition to the one-way tamper resistant screws. It might seem unnecessary to use the phillips screw first only to be removed and replaced with the one-way screws. But don't skip this important step because once the one-way screws go in, you can't remove them to adjust the alignment.If you made mistake in drilling, or if you're replacing an existing lock and the old screw holes are not at the exact same location, you can easily cover up the old holes with Bamboo Skewer and wood glue. Then a new hole near can be drilled right next the old one without breaking up the wood. Drilling pilot holes is strongly recommended because it's so easy to crack near the edge.The way the key works is slightly strange. There's no need to turn the key. Instead, just insert the key straight in, and then flip the latch open.There's another Prime-Line U 9933 that has a thinner left side. Check out how much room you have on the window before buying.

### ⭐⭐⭐⭐⭐ Good simple, additional window security.
*by S***C on November 17, 2023*

Really simple solution to adding some security for my windows. Works best when the 2 mounting surfaces are the same height and align. There is only a single position for lock and unlock. When your surfaces match it is very smooth and easy to lock and unlock.

### ⭐ Could be dangerous in a fire! Only  functions with KEY in place
*by P***W on April 15, 2017*

Could be super dangerous. The lock only functions with the key in itMy intention was to purchase them and leave them unlocked and then lock them for safety if I went away for vacation or somethingHowever you cannot even unlock the window or lock it uness the key is in placeIf you lose the key and there's a fire you're locked in your bedroom or if your child breaks the key off in the lock and there's a fire they're locked in their bedroomAmazon Stood buy this product and their customer service was wonderful but I wanted to review this so potential buyers would think about this before they put them on their windows
