Just got it and installed it. Installation is simple. Hold seems strong. Only thing I can think of is that if the L shape thing itself moves then the sheets could become lose and crumpled, but other than that it seems very good. If there is no update on this, then there is no movement and product continues to be good.

This is a cheap quality product. It hardly lasted for a week. It is a waste of money. The plastic that is used is of very low quality and does not serve the purpose. Out of 8 orders already 6 are broken. I will definitely not recommend this to anyone.

The product is just fine. It does keep the sheet in place decently well but not crisp. But the biggest disadvantage of this is that it hurts while moving around. The small plastic button hurts you when moving around, especially kids. Even if you sit where the button is, it hurts your legs. The reader might feel that it's a small problem and one can be careful not to sit there, but it's not happening; trust me. I had also thought and hence kept it on for 15-20 days but have taken 2 clips off from one side as they have been troubling :(

Not useful as shown

Till now functioning pretty gud as per the purpose.The bedsheet is stable ,not wrinkling neither it's getting deranged but sturdiness cud be an issue .Also the price is high but in all for now the purpose is served

Difficult to use, especially head end side. Keeps slipping out from under the mattress and the knob keeps falling off. Three or four already broken. Wouldn't buy again.
