I purchased one about 12 years ago and it was OK for several years untill the peak detection on the Rx side failed and quit working. Finally threw it away.

Keep in mind is not a very capable charger or versatel like a modern one and is OK only for Nicad packs. Uses a single non selectable charge rate and is only good for 4.8 Rx packs or 9.6 Tx packs of about 600Mah capacity. If you use larger capacity packs then this one will not do the job properly.
