On a Hyundai i20, it fits very well in the driver's and passenger's seat, I did not try it on the back seats.
The construction is sturdy and instructions with photos are included to secure it so that it does not come loose when you fasten the seat belt. I haven't needed to tighten it, it doesn't loosen unless you undo it.

Very comfortable, they told me at the store that it fits all seats. In a Golf, anyway, it fit perfectly and never loosened as mentioned..

3/5 because it is not the pictured product which appears to have a large handle where the belt fits comfortably, instead it has a small dolphin-shaped design in its place, consider that the width of the belt is not properly embraced, resulting in it folding at the point where it is held.

It does not provide any safety at all, you cannot adjust it to the car because it does not lock and therefore there is no proper safety during driving

The belt is perfect. I got it in the 6th month and since then I sit very comfortably. Don't listen to those who say it loosens... if you pass the strap correctly, first through the middle and then through the outer part, it doesn't move at all. Try it.

In terms of quality, the plastic piece seems very sturdy. So far, at 7 months, it has been very convenient for me! I got it in the sixth month when I didn't have enough belly for the strap to be able to sit under the belly, and I felt a lot of security. I didn't have the issue that I read from some that it loosens and that you need to tighten the strap often; for me, as soon as I placed it, I didn't need to tighten it again.

I felt safe during sudden braking, but you have to tighten it every time you sit down because it loosens

I got it for the future of the family, easy installation in the seat.
I hope I won't need to see if it's effective in braking....

If it can fit in your car, it does its job! -1 star because I doubt the safety it provides in an emergency.

Ideal for pregnant women who drive and find the seatbelt uncomfortable on the belly, it essentially forces the lower part of the belt to hug the thighs instead of the belly,

As small as it may seem, its use is so great and of utmost importance and comfort for the 7-8 months of pregnancy.

It is easy to install and easy to use. Good quality. I just think that I have seen the exact same product at a quarter of the price in a well-known department store.

Easy and stable application on the driver and passenger seat (TOYOTA AURIS & YARIS 2018). Bought one for each car. It has been very helpful for my wife throughout her pregnancy. Highly recommended, just make sure it fits your own seats.

In new cars where the seat is integrated with the backrest or the backrest is one piece from the rear side, it cannot be applied. Unless you open a hole in the seat. Unfortunately, there was no such comment before the purchase, so I wasted money. Ford Puma and KIA Sportage

The best thing on the market.. no comparison with the others that the fabric goes underneath and you have to hold the belt at 3 and it's a mess every time you get in the car... for me, it's been 4 months and I haven't even needed to tighten it. You get in and in 10 seconds you're ready to go.

It does what it promises. It is clearly value for money and although it loosens after some time, you just tighten it a bit and everything is fine. The plastic is very hard and the strap is of good quality, it has nothing to envy from other ones with double the price. (I bought it for 18€)

Very easy to apply on the seat, it holds its position steady without needing to constantly tighten it. It helped me a lot

Very easy to install. I change its position frequently and the process doesn't bother me. In some cars where there is no lever for seat adjustment but a whole bar (like in the Kia Sportage), be careful not to include the bar in the fastening.

Very good belt and very convenient! The only negative thing is that it loosens easily and often needs tightening on the seat to be stable! It helped me during pregnancy but also in the days after the cesarean section due to the incision point!

The hook is quite sturdy and holds well on the seat. Also, the strap is very long and there is no chance it won't reach!
Be careful when passing the strap not to trap and break any cables.
It can be installed in two minutes.
Wrap the remaining strap tightly after the buckle so it doesn't loosen and secure it tightly with a thick rubber band.

Very convenient belt. Safe and comfortable for every trip. I have bought 2, one for the driver's seat and one for the passenger's seat. And I will definitely give it as a gift to my pregnant friend.

Very good and practical belt. It takes up minimal space and does not bother other passengers who will sit in the seat where the belt is installed and do not use it. For the pregnant woman, she can use it easily and place it quickly. It doesn't catch your eye, but it does its job perfectly.

Flawless and affordable. Very convenient to use. Easy to install on the seat. Does not obstruct the person who does not want to use it.

Very easy to install and very convenient to use. It does not put pressure on the stomach. I have been using it since the 4th month and I am very satisfied. Besides safety, I also feel very comfortable during the journey, without worrying about any car movement.

Very convenient for use. The belt does not touch the stomach. Easy to install on the seat in two cars that I tried.

Very good product... Comfortable to use... Feeling of stability and safety... Due to its construction, it does not have a perfect fit on some seats, but it can be adjusted there as well...

Very convenient, I enjoyed it especially after the 6th month when I didn't want anything touching me (summer - car trips - pregnancy, not the perfect combination). On the negative side, I would say that it loosens relatively easily and you have to tighten it again every 1-2 days.

It is good as a belt, I just wish it would tighten a little better, it loosens very easily. Also, it would be good to have some instructions on how to tie it.

I bought it for my wife for protection. It is convenient, comfortable, and does not press on her belly. She really liked it! It kept her securely in the seat without worrying about our baby getting hurt.

I would say that it is worth more than its price. It is convenient, comfortable, does not press on the stomach because it holds the legs, it kept me stable during sudden braking, I use it as a driver and as a passenger. I can even use it after pregnancy! Unfortunately, when wearing a long dress, it doesn't look very stylish... I used it on long trips and it didn't tire me at all!
