Cumple perfectamente con su función de nivelar. Es bastante rígida.

Fatta veramente bene.

Great leveling base that is very solid! When loosened it does not flop around at all.......just the opposite......it is pretty difficult to move! I actually found that tapping the head with a small rubber hammer (I know, sounds extreme but it really isn't) is perfect for making the tiny adjustments to fine-tune the level. The bubble level agrees precisely with a large bubble level (High Precision Horizontal Bubble Cardan Level Horizontal Bubble Band Horizontal Ball Horizontal Bead Leveler 60MMAccuracy 15'/2) that I bought via Amazon. Very happy with this base!

have tried a few cheap levelling bases before from Neewer etc and they all ended up becoming loose and having play in them. I use a levelling base for video as my tripods are not bowl heads, as well as for levelling before photographic panoramas. The Sirui is not cheap, but neither are good tripods or indeed cameras. The lock down is solid and tight and even with heavy lenses there is no sag or creep. The movement of the head is beautifully fluid - a nice touch. It is clearly a step up from the cheaper brands - like everything Sirui make. They are quickly establishing themselves as a Chinese brand with premium products and quality. Like this levelling base. The only thing is I wonder why amazon ask me to rate the "warmth" of a tripod levelling base!!

Répond parfaitement aux attentes et rempli son rôle pour faciliter la mise à niveau indépendamment de la position du trépied et de la rotule (utile pour la photo de paysages,studio, panoramiques). Rapport qualité prix habituel des matériels sirui: excellentAttention, fonctionnalité je crois non documentée sur le site du constructeur et pas dans la notice: le levier de verrouillage de la base peut venir en butee contre le haut du trépied (cas par exemple sur mon sirui r-5214 avec base plate standard) et empêcher le verrouillage complet qui nécessite environ 3/4 de tour. A cet effet Le levier est debrayable en tirant dessus ce qui permet de le repositionner en arriere et de mettre le 1/2 tour de serrage supplémentaire nécessaire.Le problème ne doit pas exister pour les autres trépieds avec colonne centrale ou si on monte la colonne centrale optionnelle sur la gamme sirui rx

..... exakt gearbeitet, kein Billig-Pfusch, hochwertig und 100% zufriedenstellend. Unnötig hier das "Warum" und "Wofür" zu beschreiben, wer das Teil braucht weiss das selber .....Ich bin "happy" und das will was heissen .....
