Easy to install but convenient but I think that the price is high.

Combination Nifrek and Helmet lock can be used without problems, but I think that it can be satisfied if the quality is better a little more.
Since Helmet lock rotates 360 degrees, it is a pity that we need both hands when locking

Mudah dipasang tetapi nyaman tetapi menurut saya harganya mahal.

Nifrek kombinasi dan kunci Helm dapat digunakan tanpa masalah, tetapi saya pikir itu dapat memuaskan jika kualitasnya lebih baik sedikit.
Karena kunci Helm berputar 360 derajat, sangat disayangkan kita membutuhkan kedua tangan saat mengunci
