Hobby Warehouse did a great job of sending the product promptly. Unfortunately, I ordered the wrong battery pack, but Hobby Warehouse is being very hospitable in replacing the battery pack with the correct one. I would definitely recommend using them.

Awfully expensive for 4 AA bateries! Tearing apart old pack, I discovered it comes apart relatively easily and batteries inside can be replaced for much less cost.

The battery pack was as offered and worked correctly after charging. Delivery was quick.

The product was exactly as described, the packaging was excellent and the
delivery was unexpectedly prompt.

These batteries are good. The problem is that dremel has two similar grinders that use them. I now have both types of the (same) grinder and both grinders have 755 written on them, however the packaging for these two grinders gives them different numbers and each has a different battery pack (750-1 and 750-2).

I can't find any original grinder for replacement, and, because my old grinders don't work any more, I now have four new battery packs that won't fit. I didn't realize the old grinders were not working and had thought the battery pack was at fault.

Dremel is the problem and not the battery pack. I found suppliers on the web that have pictures of the original but when you look hard enough you find that these are old pictures, not updated, and are of the newer #755 grinder. Very confusing and frustrating. Don't buy these battery packs unless you are sure which model you need. There are no warnings that catch your attention.
