Boston SPT-135 Keyboard Bag

I've bought this bag for Kurzweil Forte SE.
Totally my equipment with sustain, cables and etc. weights about 25 kg.

This bag replaced my Proel bag.
Boston SPT-135 stiched well enought, all junctures are strong.
Inner size is exat for my keys (124.2 x 38.6 x 13.2 cm).
Main reason for buying this case - availability of transportating wheels.
For me it is hard enough to carry my equipmen only by hands.

Pros:
- In general good manufacturing
- Transportating wheels
- Very spacious outside pocket

Cons:
- A little flexure of body near wheels under big weight, while driveing

It is very convenient and functional product. It will facilitate transportating of heavy keyboards and stage pianos.
