Hopper was a great add on. The 4 pin cable needs to be able to extend the existing cable, not replace it.

Reviewed ComfortBilt 32lb Hopper Extension For HP21, HP22, And HP61

Well I wish it was designed big enough to hold a full bag of pellets.
Aso would have been nice if they had designed it so there was a deflector on the back of the lit so if you over fill it putting the pellets in it they don't fall out the back.
The unit is sturdy and well build no problems there but with a little bit more thought going into it, it could have been so much better.
